A tennis ball bounces on the floor three times, and during each bounce 23% of its kinetic energy (assuming that at the collision with the floor the ball-Earth system only had kinetic energy) is converted to internal energy
How high does it go after the third bounce, if we released it 4.0 m from the floor? A) 180 cm B) 18 cm C) 180 mm D) 240 cm
Two blocks of masses 20 kg and 9.0 kg are connected together by a light string and rest on a frictionless level surface. Attached to the 9.0-kg mass is another light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.80 m/s2, what is the tension in the second string attached to the 9.0-kg mass?
a. 23 N b. 14 N c. 16 N d. 7.2 N e. 25 N
