Question

kennedy is running down the street at 10 meters per second. he sees a double - tall latte on the road ahead of him and starts sprinting. after 5 seconds have passed, kennedy is running at 15 meters per second. assuming he does not change direction, what was kennedys acceleration?

Explanation:

Step1: Recall the acceleration formula

Acceleration \(a=\frac{v - u}{t}\), where \(v\) is final velocity, \(u\) is initial velocity, and \(t\) is time.

Step2: Identify the values

Given \(u = 10\space m/s\), \(v=15\space m/s\), \(t = 5\space s\).

Step3: Substitute values into the formula

\(a=\frac{15 - 10}{5}\)

Step4: Calculate the acceleration

\(a=\frac{5}{5}=1\space m/s^{2}\)

Answer:

\(1\)
