If a cartraveling 25.0 m/s stops uniformly in 1.20 m, (a) how long doesthe collision last, (b) what is the magnitude of the average forceon the car, and (c) what is the acceleration of the car? Expressthe acceleration as a multiple of the acceleration of gravity.

A wooden ball of weight 196 newtons is dropped vertically from a height of 100 meters above the ground. Throughout the fall, drag is present by a factor 4v due to air resistance, where v is the velocity of the ball at time t (in seconds). After how many seconds will the ball impact the ground? Assume that the net force acting on the ball is modeled by m(dv/dt) = mg – kv, where m is the mass of the ball. Also, assume that there is no initial velocity and that the acceleration due to gravity g is 9.8 meters per second squared. Do not round off intermediate steps. Round off the final answer to two decimal places.
