a body of mass 500g has momentum of 5Ns (Ns=kgm/s=unit of momentum) calculate velocity of the body?
Given,
mass(m) = 500g = 500/1000 = 1/2kg
momentum (p) = 5Ns
velocity (v) = ?
We know that p = mv
therefore v = p/m = 5/(1/2) = 10m/s
A body having 5 kg mass is traveling with a certain velocity and has 10 kgms−1 momentum. What will be its kinetic energy?
