A 2-kg ball is thrown at a speed of ____, exhibits 25j of kinetic energy.
bogdanovich [222]

Answer:

A 2-kg ball is thrown at a speed of 5 m/s, exhibits 25 J of kinetic energy.

Explanation:

Given that,

The mass of a ball, m = 2 kg

Kinetic energy of the ball, K = 25 J

We need to find the speed of the ball. The formula for the kinetic energy is given by :

K=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2K}{m}} \\\\v=\sqrt{\dfrac{2\times 25}{2}} \\\\v=5\ m/s

So,

A 2-kg ball is thrown at a speed of 5 m/s, exhibits 25 J of kinetic energy.
