Question

A booly of mass 20kg is accelarted from
Rest to 25ms in Just 6sec
calculate the work
done in accelerating the body​

Answer 1

Answer:

Explanation:

Speed = Distance/Time

Speed = 24/6

Speed = 4 m/s

Here the body is moving, so kinetic energy is experienced by the body,

W = 1/2 mv²

W = 1/2×2000×4×4

W = 1000×4×4

W = 16000

Hence, the work done is 16000 J
