A car traveling at 35 m/s suddenly accelerates to a new speed of 56.5 m/s in a time of 5.0 seconds. A) What is its acceleration? B) If the car had a mass of 2200 kg, what was the applied traction force necessary for it to accelerate? Assume NO resistance!

1. A. V = Vo + a*t.
56.5 = 35 + a*5,
a = ?

B. F = M*a.
