Question

A toy of mass 2 kg starts from rest to achieve the final velocity 10m/s. Calculate the work done on it. ​

Answer 1

Answer:

200J / s

Explanation:
It started from rest and acheived Velocity of 10m/s

So acceleration = 10m/s²

Force =  ma

force = 2*10 = 20N

Velocity is 10m/s So displacement per second = 10m

Work done = Force X Displacement

W = 20N * 10

= 200J

So the work done will be 200J/s
