Question
Kinetic energy, Ek, is given by the formula Ek=12mv2 where m is mass is the mass in kilograms and v is velocity in meters per second. The tomato is dropped. What is the velocity, v , of the tomato when it hits the ground? Assume 80.4 % of the work done in Part A is transferred to kinetic energy, E, by the time the tomato hits the ground.

Explanation / Answer
mgh = 0.804*0.5m*v^2
v = 4.973*sqrt(h) m/sec
