Asked by Lilly
A Car is travelling 20m/s when it pulls out to pass a truck that is travelling at 18 m/s. The car accelerates at 2.0m/s^2 for 7.0 seconds
B) What is the car's speed at the end of the period of acceleration?
Vi=20 m/s
Vf=18 m/s
a= 2.0m/s^2
t=7.0 Seconds
I am unsure what formula to use to solve this.

V = Vi + a*t = 20 + 2*7 = 34 m/s.
