Answer:

When it hits a wooden target, the ball exerts a force on the fibers in the wood, splintering. First, heavier objects that are moving have more kinetic energy than lighter ones: a In equation form: kinetic energy (joules) = 1/2 x mass (kg) x velocity2 (m/s) Note that: 200 kg-m2/s2 = 200 (kg-m/s2) x m = 200 N x m = 200 joules.

Answer:

90,000 J

Step-by-step explanation:

The kinetic energy (KE) of an object can be found by using the formula


k = (1)/(2) m {v}^(2) \\

m is the mass

v is the velocity

From the question we have


k = (1)/(2) * 200 * {30}^(2) \\ = 100 * 900

We have the final answer as

90,000 J

Hope this helps you
