a roller coasters accelerates from an initial velocity of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. whats the acceleration?
a) 24 m/s² b) 18 m/s²
c) 16 m/s² d) 16 m/s

Explanation:

Step1: Recall the acceleration 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 given values

Given \(u = 6.0\space m/s\), \(v=70\space m/s\), and \(t = 4\space s\).
Substitute into the formula: \(a=\frac{70 - 6}{4}\)
