Question

a body of mass 40 kg has the momentum 2000 kg m/s ; calculate:-
a) speed of the body
b) kinetic energy of the body​



PLS HELP ME OUT !!

Answer 1

Answer:

v=50 m/s

Step by step explanation

Momentum=mass×velocity

2000=40v

i) v=50m/s

KE=1/2 mv^2

Ke=1/2×40×(50)^2

KE=20×2500

KE=50000J

I hope it helps
