A ball of modeling clay weighs 0.5 kg and is thrown in a horizontal line where it hits a box weighing 5 kg and it gets stuck to the box. After the impact, the box moves at a velocity of 0.25 m/s. What is the initial velocity of the modeling clay? A. 1.12 m/s
B. 2.75 m/s
C. 3.12 m/s
D. 5.45 m/s

The speed of a baseball is 40 m/s; its mass is 0.18 kg. How fast would a 0.05 kg ball have to travel to have the same amount of kinetic energy?

A. 75.8 m/s
B. 80.2 m/s
C. 77.5 m/s
D. 64.3 m/s
