Question

A body of mass 0.05 kg moving with uniform velocity of 5 m/s . Calculate the kinetic energy?​

Answer 1

Answer:

250 joules of energy

Explanation:

Mass of body is 0.05 kg

= 0.05 × 1000g

Velocity is 5 m/s

Then K.E = mass × velocity

= 0.05× 1000 × 5

=250 joules

Answer 2

Answer:0.625 J

Explanation:

m =0.05 kg

V =5m/s

K =1/2mV²

=1/2×0.05×5²

=0.0625 J
