What is the order of magnitude of the final velocity of an object that begins from rest and accelerates at a rate of 20 meters per second2 for 5.0 seconds

The order of magnitude of the final velocity of an object that begins from rest and accelerates at a rate of 20m/s² for 5.0 seconds is 100m/s

The acceleration of a body is the change in velocity with respect to time as shown:

Given the following parameters

a is the acceleration = 20m/s²

u is the initial velocity = 0m/s

t is the time taken = 5.0seconds

Required

Final velocity "v"

Substitute the given parameters into the formula:

Hence the order of magnitude of the final velocity of an object that begins from rest and accelerates at a rate of 20m/s² for 5.0 seconds is 100m/s
