what is the change in the velocity of the biker below as he travels from point b to point c ? ..... What is his acceleration fro

Furkat [3]

The change in the velocity = 4 m/s

Acceleration = 4 m/s²

<h3>Further explanation</h3>

Given

vo = initial velocity = 4 m/s

vf = final velocity = 8 m/s

t = 1 s

Required

The change in the velocity

Acceleration

Solution

the change in velocity =

$\tt vf-vo=8-4=4~m/s$

Acceleration = ratio of a change in velocity and the time

$\tt a=\dfrac{\Delta v}{t}= \dfrac{vf-vo}{t}$

Input the value :

$\tt a=\dfrac{4~m/s}{1~s}=4~m/s^2$
