Question

Two bowling balls of different masses collide while accelerating at 1.875 ms2
. The first ball, rolling to the right, weighs 7 kg. The second ball, rolling to the left, weighs 4 kg. What force does the bowling ball weighing 7 kg exert on the bowling ball weighing 4 kg?(1 point)

Answer 1

Use Newton's 2nd law on the 4 kg ball: F = m a = 4 kg × 1.875 m/s^2 = 7.5 N. The 7 kg ball pushes the 4 kg ball to the right, so the force is 7.5 N to the right.
