Question

calculate the acceleration of a car that goes from 30 m/s to a speed of 65 m/s in 5 seconds.

Explanation:

Step1: Identify the formula

The formula for acceleration is \(a=\frac{v - u}{t}\), where \(v\) is the final velocity, \(u\) is the initial velocity, and \(t\) is the time.

Step2: Substitute the values

Given \(u = 30\space m/s\), \(v=65\space m/s\), \(t = 5\space s\). Substitute into the formula: \(a=\frac{65 - 30}{5}\).

Step3: Calculate the numerator

\(65-30 = 35\). So the formula becomes \(a=\frac{35}{5}\).

Step4: Perform the division

\(\frac{35}{5}=7\space m/s^{2}\).

Answer:

\(7\space m/s^{2}\)
