Question

A body of mass 10 kg has a momentum of 300 kg m/s. Calculate the kinetic energy of the body​

Answer 1

Answer:

Formula is 0.5*mv^2

Explanation:

so the result is 0.5*10*300^2.

=450000

Answer 2

Explanation:

mass ( m) = 10 kg

momentum = 300 kg m/s

velocity ( v ) = ?

momentum = mass x velocity

300 = 10 x v

300/10 = v

30 = v

K.E = 0.5 mv²

= 0.5 x 10 x 30²

= 0.5 x 10 x 900

= 4500
