Question

A force of 10N acts on a body for 3.If mass of the body is 5g,calculate the change in velocity​

Answer 1

Explanation:

Here,  F=10N,t=3μs

=3×10−6s;

M=5g=5×10−3kg

Now, impulse =Ft=10×3×10−6

=3×10−5Ns

Also, impulse = change in momentum

=Mv2−Mv1

=M(v2−v1)

∴(v2−v1)=Mimpulse=5×10−33×10−5

=6×10−3ms−1
