First, we need to convert the velocity from miles per hour to meters per second for both cases:
- 60 mph = 26.82 m/s
- 14 mph = 6.26 m/s
Assuming the mass of the bowling ball is 6 kg, we can calculate the kinetic energy for both cases:
- KE1 = 0.5 * 6 kg * (26.82 m/s)^2 = 2273.3 J
- KE2 = 0.5 * 6 kg * (6.26 m/s)^2 = 117.1 J
Therefore, the kinetic energy of the bowling ball when rolling at 60 mph (26.82 m/s) is 2273.3 J, and the kinetic energy of the bowling ball when rolling at 14 mph (6.26 m/s) is 117.1 J.
