Question

a body of mass 50 kg has a momentum of 400 kg MS power minus 1 find its velocity​

Answer 1

Answer:

400-50=350...is the momentum of the body

Answer 2

Answer:

m = 50 kg, p = 400 kg ms-1

Since p = mv

∴ v = p/m = 400/50 = 8 ms-1

Kinetic energy of the body = 1/2mv2

= 1/2 x 50 x (20)2 = 25 x 6000

= 150000 J

(ii) Velocity of the body v = 60 ms-1
