Problem
A toy car of mass 0.80 kg moves on a horizontal surface. It is subjected to the following horizontal forces: a 5.0 N pull to the right (along the direction of motion), 1.0 N air resistance to the left, and 0.60 N kinetic friction to the left.
(a) Calculate the magnitude and direction of the car’s acceleration.
(b) If the pulling force is adjusted so that the car accelerates to the right at 4.0 m/s2, find the new value of the pulling force.
