2.2 What is Motion?
A 50-g ball traveling at 25.0 m/s is bounced off a brick wall and rebounds at 20.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.50 ms, what is the magnitude of the average acceleration of the ball during this time interval?0%

Two blocks of masses 22 kg and 9 kg are connected together by a light string and rest on a frictionless level surface. Attached to the 9-kg mass is another light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.7 m/s2, what is the tension in the second string attached to the 8-kg mass?

A ball of relatively low density is thrown upwards. Because of air resistance the acceleration while traveling upwards is −10.8 m/s2. On its trip downward the resistance is in the opposite direction, and the resulting acceleration is −8.8 m/s2. When the ball reaches the level from which it was thrown, how does its speed compare to that with which it was thrown?

11.3 Harmonic Motion and Energy
A runaway railroad car, with mass 30 × 104 kg, coasts across a level track at 2.0 m/s when it collides with a spring-loaded bumper at the end of the track. If the spring constant of the bumper is 4.0 × 106 N/m, what is the maximum compression of the spring during the collision? (Assume the collision is elastic.)0%
