Question

The mass of a cannon ball is 10 kg. If the speed of the cannon ball is 50 m/s in

position A and E (just before hitting the ground), Calculate:

Answer 1

Step-by-step explanation:

Kinetic Energy = 0.5(Mass)(Velocity2)

Kinetic energy= 0.5 × 10kg × (50m/s)2

Kinetic Energy = 5kg × 2500m/s

Kinetic energy = 125000 J ( Ans)
