A coin that is tossed straight up into the air. After it is released, it moves upward, reaches its highest point and falls back down again. Use one of the following choices (A through G) to indicate the acceleration of the coin during each of the stages of the coin's motion described below. Take up to be the positive direction. Answer choice J if you think that none is correct. A. The acceleration is in the negative direction and constant. B. The acceleration is in the negative direction and increasing. C. The acceleration is in the negative direction and decreasing. D. The acceleration is zero. E. The acceleration is in the positive direction and constant. F. The acceleration is in the positive direction and increasing. G. The acceleration is in the positive direction and decreasing. The coin is moving downward. A OF ΟΕ B

We start with some review problems A crate of mass 20.0 kg rests on a level surface, with a coefficient of kinetic friction 0.219. You push on the crate with an applied force of 297 N. What is the magnitude of the crate s acceleration as it slides?     12.70 m/s^2     14.85 m/s^2     6.35 m/s^2     20.79 m/s^2

An Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. The masses have the values mj = 26.0 kg and m2 16.0 kg. Assume that the rope and pulley are massless and that there is no friction in the pulley. What is the magnitude of the masses' acceleration a? т, m/s? What is the magnitude of the tension T in the rope? m, T = N

A crate is pulled using a rope angled at 45° upwards from the horizontal. If the crate slides along the floor with a constant velocity, calculate the magnitude of the applied force. 45° 15.2 kg Hk = 0.37 Fama ama 23

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

A car of mass 822 kg is traveling 26.4 m/a when the driver applies the brakes, which lock the wheels. The car skids for 4.47 s in the positive x direction before coming to rest. What is the cars acceleration in m/ s2? what magnitude force in N acted on the car during this time? How far in m did the car travel?

An Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. The masses have the values M(1): 27.0Kg and m(2)= 11.0Kg. Assume that the rope and pulley are massless and that there is no friction in the pulley. What is the magnitude of the masses' acceleration a? What is the magnitude of the tension T in the rope?
