A ball with a mass of 0.15 kg rolling at 2.7 m/s rolls down into a ditch that is 2.2 m deep. Assuming a complete transformation of energy, what is the ball's velocity at the bottom of the ditch?

Answer:

6.57 m/s

Explanation:

gravitational potential energy= maximum kinetic energy

mgh= 1/2mv*2

(0.15)(9.8)(2.2)= 1/2(0.15)v*2

3.234= 1/2(0.15)v2

v2= 43.13

v=6.56 m/s
