What is the velocity. U of the tomato when it hits the ground? Assume 947 % of the work done in Part A s transferred to kinetic energy, E, by the time the tomato hits the ground Express your answer with the appropriate units Hints v= 11.51

The weight of the tomato is 105 g.
Please work problem. I can't figure out what I'm doing wrong

Answer 1

Given , m = 105 g = 0.105 kg , W = 13 J

Since 94.7% of work done is converted to Kinetic energy(Ek)

Ek = (94.7/100)*13 = 12.311 J

So,

Ek = (1/2)*m*v^2

12.311 = (1/2)*0.105*v^2

v^2 = 234.495

v = 15.313 m/s

Thus, velocity of tomato is 15.313 m/s
