Question

A car accelerates from 5 m/s to 27 m/s in 10 seconds. What is the acceleration in m/s2 ?

Answer 1

2.2m/s²

Step-by-step explanation:

Given parameters:

Initial velocity = 5m/s

Final velocity = 27m/s

Time = 10s

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time;

It is mathematically expressed as;

A =
`(v-u)/(t)`

v is the final velocity

u is the initial velocity

t is the time taken

Insert the parameters and solve;

A =
`(27 - 5)/(10)` = 2.2m/s²
