    Graphing with time, velocity, and acceleration.

    The velocity of a car on a straight stretch of highway is recorded every 5 seconds. The data is in the table below. A negative velocity means that the car is traveling east. A positive velocity means it is traveling west. Make a velocity versus times graph, that is, plot velocity on the vertical axis and time on the horizont

    Cosine Curve and Total Energy

    ATTACHMENT1 shows the graph of x(t) for a mass M= 2.4 kg suspended on a spring of force constant k, executing SHM. a. From information on the graph, develop x(t) with numerical values and units for the constants of the SHM. b. Find the force constant, k, of the spring.

    Value of a Graph Part Written

    An object moves on an x axis with amplitude 5.0 cm. ATTACHMENT1 shows a graph of its x coordinate versus time. a. From the graph, by observation, write the number and units as called for in the spaces on the ATTACHMENT1. b. Using the values from part a, write x(t) for this SHM. c. Finding v(t) by derivative dx/dt, find the m

    Magnitude and direction of water from a water cannon

    A water cannon fires a steady stream that reaches a height of 1000 ft and strikes the same horizontal plane 4300m from where it is fired (hint: maximum height is 1000 ft). What is the velocity (magnitude and direction) of the water leaving the cannon?

    Position Vector r(t) with Unit Vectors

    A point moves in the x,y plane. Position vector r(t), from the origin to the point, gives the location of the point at time, t. Unit vectors are i and j, each 1 unit long in the x and y directions respectively. Write answers assuming units of distance in meters and times in seconds. Given: r(t)= (2 t^2 + 15) i - (8 t - 9) j
