Question

2. a) A force of 1000N is acting on a body for 10s. then find impulse produced.
b) A ball of mass 5kg is moving with a velocity of 10m/s. Then find momentum of the
body.​

Answer 2

Explanation:

Here, F=1000N,t=3μs

=3×1000−6 s;

M=5g=5×1000−3 kg

Now, impulse =Ft=10×3×1000−6=3×1000−5 Ns

Also, impulse = change in momentum=Mv 2 −Mv 1=M(v 2 −v 1 )

∴(v 2 −v 1 )= Mimpulse = 5×1000−3

3×1000−5=6×1000−3 ms −1
