Question

A body of mass 50kg has a momentum of 10^3 kg m/s. What will be its kinectic energy?​

Answer 1

Answer:

K.E is 10⁴ J

Explanation:

K.E = 1/2 mv² = $\frac{1}{2}$$\frac{m^{2} v^{2} }{m}$ = $\frac{p^{2} }{2m}$

      = $\frac{(10^{3}) ^{2} }{2 X 50}$

      = $\frac{10^{6} }{10^{2} }$

      = 10⁴ J
