Question

A car accelerates at 2 meters per second per second. Assuming the car starts from rest, how much time does it need to accelerate to a speed of 30 m/s?

Answer 1

use the constant acceleration equation
v = u + at
where u = initial velocity, a = acceleration , v = velocity at time t and t = time

Answer 2

so replace v with, 30 , u = 0 and a = 2 and find t

Answer 3

30 = 0 + 2t
find t

Answer 4

15 = t, Thank you very much.
