Question

A conveyer 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? 40 J 80 J 160 J 1,600 J

Answer 1

Kinetic energy of the box=80J

Explanation:

mass of the box=40 Kg

velocity of box= 2 m/s

Kinetic energy= 1/2 mV²

KE= 1/2 (40)(2)²

KE=80J

Thus kinetic energy of the box=80 J

Answer 2

Answer:

80j
