A scientist wanted to move a golf ball and a bowling ball to both reach 15 mph. What would the scientist have to do differently for the bowling ball than the golf ball to reach his goal?

To move both the golf ball and the bowling ball to reach a speed of 15 mph, the scientist would have to apply different amounts of force to each of them. The bowling ball, being significantly heavier than the golf ball, would require a greater amount of force to achieve the same velocity. The scientist would need to exert more force on the bowling ball compared to the golf ball to reach the target speed of 15 mph.
