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. drag and match the question with the correct answer

Explanation:

Step1: Calculate speed for each ball

Speed formula: \(v=\frac{d}{t}\) (where \(v\) is speed, \(d\) is distance, \(t\) is time)
For Ball 1: \(v_1=\frac{100}{10}=10\ \text{cm/s}\)
For Ball 2: \(v_2=\frac{50}{20}=2.5\ \text{cm/s}\)
For Ball 3: \(v_3=\frac{100}{20}=5\ \text{cm/s}\)
For Ball 4: \(v_4=\frac{50}{10}=5\ \text{cm/s}\)

Step2: Match questions with answers

• Which ball had the fastest speed? Ball 1 (\(10\ \text{cm/s}\))
• Which ball moved at the same speed as Ball 3? Ball 4 (\(5\ \text{cm/s}\))
• Which ball had the slowest speed? Ball 2 (\(2.5\ \text{cm/s}\))
• Which ball was thrown with the greatest force? Ball 1 (since force is related to speed, and Ball 1 has the highest speed among them)

Answer:

Which ball had the fastest speed? Ball 1
Which ball moved at the same speed as Ball 3? Ball 4
Which ball had the slowest speed? Ball 2
Which ball was thrown with the greatest force? Ball 1
