Question

1. bob is running down the street at a velocity of 2m/s before he crashes into a tree because he was scrolling on tik tok. he gets up after 1 second and trots over to pick up his phone at 4 m/s, without stopping and continuing his run. what is bobs acceleration? 2 m/s/s -2 m/s/s 4 m/s.5 m/s/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: Identify the values

Here, \(u = 2m/s\), \(v=4m/s\), and \(t = 1s\).

Step3: Substitute the values into the formula

Substitute the values into \(a=\frac{v - u}{t}\), we get \(a=\frac{4 - 2}{1}\).

Step4: Calculate the acceleration

\(a=\frac{2}{1}=2m/s^{2}\) (or \(2m/s/s\)).

Answer:

A. 2 m/s/s
