Question

A 2.0 x 103 kg car accelerates from rest under the influence of two forces. One is a forward force of 1100 N provided by traction between the wheels and the road. The other is a 950 N resistive force due to various frictional forces. a) What is the net force on the car? b) At the moment the car reaches 5.0 m/s, calculate its kinetic energy. c) How far must the car travel for its speed to reach 5.0 m/s?

Step 1

Given: Forward force (F1) = 1100 N Resistive force (F2) = 950 N Net force (Fnet) = F1 - F2 Fnet = 1100 N - 950 N Fnet = 150 N Show more…
