Question

A car moving at a velocity of 25 m/s [N] accelerates at a constant rate of 1.5 m/s2 [N] for 4.0 s. What is the final velocity of the car?

Answer 1

Vf = 31 m/s

Step-by-step explanation:

Have to use the Final Velocity Formula - Vf = Vi + a * t

Vf = Final Velocity

Vi = Initial Velocity

a = acceleration

t = time

* = multiply

Vf = 25 + 1.5 * 4

Vf = 25 + 6

Vf = 31 m/s

The final velocity of the car is 31 m/s.
