A 7.0 kg bowling ball is in a bowling lane with a velocity of 5 m/s. What is the kinetic energy of the ball?

Sagot :

The formula in finding the kinetic energy of an object is [tex] \frac{1}{2}mv^{2} [/tex].

KE = [tex] \frac{1}{2}mv^{2} [/tex]
     = [tex]( \frac{1}{2})[/tex](7.0 kg)[tex] (5 m/s)^{2} [/tex]
     = (3.5 kg)(25 m/s)
     = 87.5
     *We're going to round it off to its least significant value so that we can get the final answer.

The kinetic energy of the ball is 90 J.
