Question

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?

Answer 1

we know that a= velocity by time and for velocity = acceleration × time so velocity=at

Answer 2

Answer:

d = ½at²

speed = d/t = ½at² / t = ½at

So if the car accelerated at 5 meters per second per second, and did so for 10 seconds, its average speed would be 5*10/2 = 25 meters per second
