Question

Find the momentum of a body of mass 100 gram having kinetic energy 500J.

Answer 1

Kinetic energy= 500J
mass=100g= 0.1kg
momentum (p)=?
relation between kinetic energy and momentum
e^k= p^2/2m
e^k= p^2/2×0.1
e^k=p^2/0.2
500J×0.2=p^2
100J=p^2
p=_/100J
p= 10

Answer 2

Momentum=mass×velocity
Kinetic energy=1/2×mass×velocity^2
Kinetic energy=500J
500=1/2×.1×v^2 [100gram=.1kg]
100=v^2
v=10 m/s
Momentum=mv
Momentum=10×.1
MOMENTUM =10kgm/s
