Question

A bowler throws her ball at the pins. The ball begins at rest, rolls for 5 s and travels 18.29 m (60 ft.). What was the ball’s average speed?

A. 3.658 m/s
B. 6.174 m/s
C. 12.35 m/s
D. 18.29 m/s

Answer 1

The ball's average speed is calculated by dividing the distance traveled, 18.29 meters, by the time taken, 5 seconds, resulting in 3.658 m/s.

Step-by-step explanation:

To calculate the average speed of a bowling ball, you can use the formula speed = distance/time. In this scenario, the ball travels 18.29 meters in 5 seconds. Using the formula, the average speed would be 18.29 m / 5 s = 3.658 m/s. So, the ball's average speed was 3.658 m/s, which corresponds to option A.
