Check my work on Average Force!

A 1,662 kg car goes from 14 m/s to 29 m/s in 19 secs.

What is the average force acting upon it? Write your answer to two decimal places.


Attempt:

Mass = m = 1,662 kg
Initial Velocity = V_i = 14 m/s
Final Velocity = V_f = 29 m/s
Time = t = 19 secs
Acceleration = a = Δvelocity/time = (V_f - V_i)/t = 15/19 = 0.7894736842105263 m/s²
Force = F = m x a = 1,662 x 0.7894736842105263 = 1312.105263157895 N

Answer:

Average Force = 1312.11 N

Is the answer correct?
