Question

Calculate the work done in moving a body of mass 20 kg from rest through a distance of 2 m with an acceleration of 5 m/s^2​

Answer 1

F=M*A

So, 20*5= 100N

By,

W=F*S

W=100N *2m

W=200Nm or Joules

Answer 2

Answer:

m=20 kg ,  a=5m/s^2  ,  s=2m

work done , w = F S

                       = ma . s

                       =  (20) (5) (2)

                       = 200 J

 

hope this helps u ..
