A car travels from rest with a constant acceleration “a” for “t” seconds. What is the average speed of the car for its journey if the car moves along a straight road?

Explanation

The car starts from rest, so u = 0
The distance covered in time t
`s=1/2at^2`
Average speed =`("Total distance")/("Time taken")`
`V=((at^2//2))/t=(at)/2`
