Question

The net force of a car taking a bend in the road is 79 N 38° East of North If the force of friction on the car tires is due East, what is

the force on the car from the motor as it takes the bend if it only acts North? (Angle to the nearest degree)

Answer 1

Draw the force diagram:

The magnitude of the force $F$  on the car from the motor is

$$F=F_\text{net}\cos38°=62\text{ N}.$$
