Question

What is the kinetic energy of a baseball moving at 10 m/s that has a mass of .5 kg?

Answer 1

Answer:

25J

Explanation:

Given that,

• velocity = 10 m/s
• mass = 0.5kg

Kinetic energy = $\frac{1}{2}$ × mass × velocity²

                        = 0.5 ×0.5 ×10²

                         = 25 J
