Question

The kinetic energy of a body is 0.625×10j . Find the velocity if it's mass is 50 kg

Answer 1

Answer:

0.5 m/s

Explanation:

Kinetic energy = Half of Product of mass and square of velocity.

625×10^-2= 1/2× 50 × v^2

625/25 × 10^-2 = v^2

25/10^2 = v^2.

v= root (25/10^2)

v= 5/10

v= 0.5 m/s.

Answer 2

Answer is velocity = 5 m/s
