Please see the attached file for full problem description. Please give step by step answers with solutions. I am learning so much by using your service just by seeing these done. Thanks!

Please give the solution and a step-by-step way to figure the answers out please. Learning is important. Use the data for all these questions on position versus time. The graph points are at 8 meters t=0 seconds. -4 meters at 1 second, -8 meters at 2 seconds, -4 meters at 3 seconds, 0 meters at 4 seconds and 28 meters at 5

Hi, please give the step by step solutions so I can see how you got the answers and understand it. The graph on the page is a velocity versus time graph. The time is in seconds. The graph has points at (0,20),(5,40),(10,60),(15,80),(15,60),(15,40),(15,20),(15,0),(15,-20),(15,-40),(20,-40), and then the next point is approxima

Please give step by step answers please. 1) The position versus time for a certain object moving along the x-axis is shown. The object's initial position is -3meters. The graph is position in meters for the y axis and the x axis is time in seonds. Point one on the grpah for 0 sec. is at (0,-3), 1 sec at (1,3), 2 sec (2

1) The position versus time for a certain object moving along the x axis is shown. The objects initial position is -3m. The graph points since I cannot draw it start at (0,-3),(2,9),(3,6),(4,4),(5,4),(6,0),(7,-4) and (9,0). a) Find the average velocity in the time interval 0s to 2s in m/s. b) Find the average velocit

Questions: 1) Two ants race across a table that is 72.5 cm long. One travels at 4.02 cm/s and the other at 2.7 cm/s. When the first one crosses the finish line, how far behind is the second one? Answer in units of cm. 2) The position of a car coasting down a hill was observed at various times and the results are summariz

Hi. Can someone please walk me through how to do the following problem? On a vacation flight, you look out the window of the jet and wonder about the forces exerted on the window. Suppose the air outside of the window moves with a speed of approximately 150 m/s shortly after take-off, and that the air inside the plane is at a

At t=0, a wheel rotating about a fixed axis at a constant angular acceleration has an angular velocity of 2 rad/s. Two seconds later it has turned 5 complete revolutions. What is the angular acceleration of this wheel? ============================================== Answer: a) 17 rad/s^2 b) 14 rad/s^2 c) 20 rad/s^2 d) 23 ra

A loudspeaker is placed between 2 observers who are 120m apart, along the line connecting them. If one observer records a sound level of 60.0 dB and the other records a sound level of 90 dB, how far is the speaker from each observer? Hint: use the equation which relates to the difference between the decibel levels to the distanc

All work must be shown step by step, any answers given without proper justification will not be accepted. Keep track of units and use proper notation. An object is dropped from a tall building, If the air resistance is proportional to the square of the velocity, then (dv/dt)=-32(ft/sec^2)+kv^2 where k is a constant. Show th

2 buses, 385 miles apart, are traveling directly toward each other on the same road. One is traveling 60 miles an hour and the the other is traveling 50 miles an hour. After how long will they meet?

One end of a long wire under tension is moved up and down sending a wave along it. Assume the wire lies along an x axis with the moving end at the origin. The equation giving displacement y, in meters, of points on the wave is: (1) y= (.06 m) sin (5 x - 25 t) a. From given constants, calculate the value and units of the quan

An old fashioned perfume atomizer operates by the user squeezing a bulb which sets up a rapid flow of air through a horizontal tube. The reduction in pressure due tothis rapid flow causes perfume to be sucked up a vertical tube from the bottle and then expelled from the horizontal tube along with the air. For simplification, we

How do i rearrange Bernoulli's equation to eliminate the pressure and make velocity the subject?

On a frictionless table, a spring has one end fixed and the other attached to block M. Block m, is in contact but not attached to M. The spring, originally unstressed was compressed from 0 to -S. There the spring system was released from rest. See ATTACHMENT for a diagram with parameters and basic physics. Block M= 2.0 kg, blo

A mass M attached to an ideal spring with force constant k executes SHM on a horizontal frictionless table. It has a total energy of 1.0 Joule and amplitude .10 m, and its maximum speed when location x= 0, is 1.2 m/sec. a. find k and M and the period T. b. If the initial location of the mass is at x= +Xm, develop x(t), and v(

A point p moves in a circle of radius R, at constant angular velocity w. The origin of an x axis is at the center of the circle. Represent as vectors, the location, the velocity and the acceleration of point p, then show the x direction projection of these three vectors to represent the location, the velocity and the acceleratio

Task: Suppose a pulsar with a speed of 0.96c approaches Earth, and a rocket with a speed of 0.995c heads toward the pulsar (both speeds measured in Earth's frame of reference). If the pulsar emits 10 pulses per second in its own frame of reference, at what rate are the pulses emitted in the rocket's frame of reference?

Specifically, Train A, traveling 70 miles per hour (mph), leaves Westford heading toward Eastford, 260 miles away. At the same time Train B, traveling 60 mph, leaves Eastford heading toward Westford. When do the two trains meet? How far from each city do they meet? Thanks.
