Kinetic energy
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.
Part B
The tomato is dropped. What is the velocity, v, of the tomato when it hits the ground? Assume 94.2 % of the work done in Part A is transferred to kinetic energy, E, by the time the tomato hits the ground.

Two objects are dropped simultaneously from an initial height of 100m, with an initial velocity of zero. They fall straight down. For mass 1, you can ignore air drag. For mass 2, air drag DOES affect the motion.
