Aconveyer belt moves a 40 kg box at a velocity of 2 m/s. what is the kinetic energy of the box while it is on the conveyor belt?

Answer : The kinetic energy of the box is, 80 J

Explanation :

The formula used for kinetic energy is:

where,

K.E = kinetic energy = ?

m = mass = 40 kg

v = velocity = 2 m/s

Now put all the given values in the above formula, we get the kinetic energy of the box while it is on the conveyor belt.

Thus, the kinetic energy of the box is, 80 J

your answer is c! hope this : )
