(a) What is the acceleration of an automobile that goes from a dead stop to a speed of 50

Question

m/s in 5 s? (b) Assume that you are driving an automobile that has a mass of 800 kg. If this
acceleration is applied, how much force (in Newtons) is applied?

Answer 1

a. a = (Vf-Vo) / t = (50-0)/5=10 m/s^2.

b. Fap = ma = 800 *10 = 8000 N.
