Question

A constant force of 12.5 N acts on a body for 2 sec. Find the change in momentom.​

Answer 1

Answer:Force =ma

12.5=ma

a=12.5/m

Initially velocity =u

And now v=u+25/m (v=u+at)

Initial momentum p =m*u

P(u)=mu

P(v)=m*v

=m*(u+25/m)

=mu+25

Change in momentum = p(v)- p(u)

=mu+25 - mu

=25

Hope this helps

Thank you
