Question

the linear momentum of a body of mass 2 kg is 16kg ms . what is its kinetic energy

Answer 1

Ke = 1/* mv2=1/2p^2/m=1/2*16*16/2=64 j

Answer 2

Answer:

Given

mass =2kg

linear momentum = 16kgm/s

Sol

We know that

P = m × v

P/m=v

16/2=v

8=v

v = 8 m/s

now

we have to find kinetic energy

k = 1/2 mv2

k = 1/2×2×64

k= 64 J ans
