Question

The kinetic energy of a machine is 500 Joules. Calculate its mass, it moves with velocity of 5mls kinetic energy =500 Joules, velocity =5mls,mass=?

Answer 1

Answer:

kinetic energy of machine = 500 J

velocity of machine = 5 m/s

let mass of machine be m.

kinetic energy = ½ mv²

500 = ½ m (5)²

500 = ½ m × 25

1000 = m × 25

m = 1000/25

m = 40 kg

hence, mass of the machine is 40 kg
