Question

how fast can you throw a tennis ball? the speed of the ball is determined by the distance the ball travels in a certain amount of time. and the speed of the ball is determined by how much force you use to throw the ball. here is a data table about the motion of four tennis balls. time and distance ball distance traveled (cm) time taken to cover the distance (seconds) ball 1 100 10 ball 2 50 20 ball 3 100 20 ball 4 50 10 drag and match the question with the correct answer. which ball had the fastest speed? which ball moved at the same speed as ball 3? which ball had the slowest speed? which ball was thrown with the greatest force?

Explanation:

Step1: Calculate speed for each ball

Speed formula: $v = \frac{d}{t}$
Ball1: $\frac{100}{10}=10$ cm/s; Ball2: $\frac{50}{20}=2.5$ cm/s; Ball3: $\frac{100}{20}=5$ cm/s; Ball4: $\frac{50}{10}=5$ cm/s

Step2: Match questions to answers

1. Fastest speed: Ball1 (10 cm/s)
2. Same speed as Ball3 (5 cm/s): Ball4
3. Slowest speed: Ball2 (2.5 cm/s)
4. Greatest force (assumes same mass, so highest speed = greatest force): Ball1

Answer:

1. Which ball had the fastest speed? → Ball1
2. Which ball moved at the same speed as Ball3? → Ball4
3. Which ball had the slowest speed? → Ball2
4. Which ball was thrown with the greatest force? → Ball1
