Question

a constant force acts on a body of mass 50 grams at rest for 2 seconds. if the body moves through 27 minutes during that time, find the impuls​

Answer 1

Answer:

Given :   u=0

Let the velocity of body after t seconds  be v.

Using      v=u+at                  where  a=mF

∴   v=0+mFt                    ⟹v=mFt

Distance covered in another t seconds      x=vt       

∴    x=mFtt                         ⟹F=t2mx
