Question

A 5.0 kilogram initially at rest is accelerated by a force of 25 newtons such that it attains 5.0 x 102 joules of kinetic energy. Determine the final speed of the object.

Answer 1

Below

Step-by-step explanation:

Final Kinetic Energy = 1/2 m v^2

5 x 10^2 J = 1/2 ( 5 kg)(v^2 )

1000 / 5 = v^2

200 = v^2

v = 10 sqrt 2 or 14.1 m/s
