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?

Text Solution

Verified by Experts

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