Question

A car starts from rest and reaches a speed of 20m/s in 5 second what is the acceleration of the car

​

Answer 1

The car's acceleration is 10 m/
`s^(2)`

Step-by-step explanation:

The "acceleration" tells you how the velocity's rate changes over a specific period of time.

The formula is: a (acceleration) =
`(change in velocity)/(change in time)`

The velocity changed from 0 m/s to 20 m/s while time changed from 0 sec. to 5 sec.

Therefore: a =
`(20 m/s)/(5 s)` = 10 m/
`s^(2)` (this refers to the rate at which the car's velocity changed over time)
