A. how much work is done when a 185g tomato is lifted 15.0m? b. the tomato is dropped. what is the velocity, v, of the tomato when it hits the ground? assume 82.1 % of the work done in part a is transferred to kinetic energy, e, by the time the tomato hits the ground.

v = 18.92 m/s

Explanation:

given,

mass of the tomato = 185 g = 0.185 Kg

height of the lift, h = 15 m

work done by lifting the tomato will be equal to the potential energy gained by the tomato.

W = PE

W = m g h

W = 0.185 x 9.8 x 15

W = 27.195 J

now,

E = 82.1 % of KE

  0.07594 v² = 27.195

      v² = 358.099

      v = 18.92 m/s

speed of the tomato at which it hits ground is equal to 18.92 m/s.

the bal will not change its velocity.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
