Question

A student drops a water balloon out of a dorm window 16 m above the ground. What is its speed when it hits the ground?

Answer 1

Answer #1

All of the potential energy of balloon will be converted into its kinetic energy on reaching the ground

Hence ½mv² = mgh so v = √2gh = √2×9.8×16 = √313.6

v = 17.7 m/s
