An appliedforce of 6 Newtons acts in the direction of motion of a block of mass 9 Kg, with the mass being pulled across the floor against a frictional force of .6 Newtons. Assume that the block moved the distance 'y' in this process.
* What is the net force on the object?
* How much work does the net force do on the object
Just before it is struck by a racket, a tennis ball weighing 0.560 N has a velocity of (20.0i-4.0j) m/s. During the 3.00 ms that the racket and ball are in contact, the net force on the ball is constant and equal to (-380i+110j)N. What is the x-component of the impulse of the net forceapplied to the ball? What is the y-componen
A .51kg object is at rest. a 2.70 N force to the right acts on the object during a time interval of 1.32s
A) what is the velocity of the object at the end of this time interval? (in m/s)
B) at the end of this interval, a constant force of 3.86N to the left is applied for 3.02s
What is the velocity at the end of the 3.02s?
A satellite at r(0) =10,000 miles from the center of the earth is given an initial velocity v(0) = 20,000 ft/s in the direction shown(getting further away). Determine the magnitude of the transverse component of the satellites velocity when r=20,000mi.(the radius of earth is 3960mi.)
If a body with a mass of X kg is sliding across a horizontal floor with an initial velocity of Y meters per second and comes to rest after Xmeters, how do you calculate the force of friction that stopped the object?
A car brakes in an emergency, the moment the brakes are first applied is t=0. the car's distance, s, from the point at which the brakes were first applied is given by:
S = -0.1t^3 + 20t + 0.1
(i) Differentiate s to find formulae for the velocityand acceleration.
(ii) Find the time at which the car comes to a stop.
Could you please provide a force vs. time graph for the following:
a) a car moves away from the origin with constant velocity
b) car moves tward the orgin with constant velocity
c) moves away from origin is a steady decreasing velocity
d) moves away from the origin, speeds up, then slows down
e) toward to ori
You can push a 335 N trunk up a 20.0° inclined plane at a constant velocity by exerting a 209 N force parallel to the plane's surface. What force must be exerted on the trunk so that it would instead slide down the plane with a constant velocity?
