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 distance covered in time t
s = `(1)/(2) at^(2) `
Average speed = `(" Total distance " )/("Time taken " )`
`v = (("at"^(2)))/(t)`
= `(at)/(2) `
