Question

if a cars velocity increases to 30m/s from rest in 6.0s, what is its acceleration? answer:____m/s²

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 \(v = 30m/s\), \(u=0m/s\) (starts from rest), and \(t = 6.0s\).
Substitute into the formula: \(a=\frac{30 - 0}{6.0}\)

Step3: Calculate the acceleration

\(a=\frac{30}{6.0}=5m/s^{2}\)

Answer:

\(5\)
