Question

1. determine the distance that a tennis ball will travel in 2.5 seconds if it has a velocity of 45 m/s.

125 meters
90 meters
112.5 meters
115 meters

Explanation:

Step1: Recall the formula for distance

The formula for distance \(d\) when velocity \(v\) and time \(t\) are known is \(d = v\times t\).

Step2: Substitute the given values

Given \(v = 45\space m/s\) and \(t=2.5\space s\), substitute into the formula: \(d=45\times2.5\).

Step3: Calculate the product

\(45\times2.5=(40 + 5)\times2.5=40\times2.5+5\times2.5 = 100+12.5=112.5\)

Answer:

112.5 meters
