Question

A car accelerates from 45m/s to 0 m/s in 10 seconds what is the average acceleration of the car

Answer 1

Answer:
`-4.5 m/s^2`

Step-by-step explanation:

The average acceleration of the car is given by:

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

where

u = 45 m/s is the initial velocity

v = 0 m/s is the final velocity

t = 10 s is the time taken

Substituting the numbers into the equation, we find

`a=(0 -45 m/s)/(10 s)=-4.5 m/s^2`
