How fast will a car be going after 5 seconds when the car accelerates from rest at a rate of 6 meters per second squared?

Answer 1

30 m/s

Use the kinematic equation: vf = vi + at,

where:

vf is final velocity (?), vi is initial velocity (0 m/s), a is acceleration (6 m/s2), and t is time (5 s).

Plug the known values into the equation and solve.

vf = 0 + (6 m/s21)(5 s) = (6 m/s)(5) = 30 m/s

Answer 2

The speed, in this case, is the acceleration multiplied by the time.

Answer 3

Acceleration is not measured in metres per second but in metres per second-squared. Assuming the latter, the car will be going at 30 metres per second.
