1. A 2,284-kg car is moving down a road with a slope (grade) of 13% at a constant speed of 11 m/s. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e., down the slope)

2. A 1,892-kg car is moving down a road with a slope (grade) of 12% while slowing down at a rate of 3.7 m/s^2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e., down the slope)

3. A 2,254-kg car is moving down a road with a slope (grade) of 30% while speeding up at a rate of 1.1 m/s^2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e., down the slope)

4. A 1,834-kg car is moving down a road with a slope (grade) of 11% while speeding up at a rate of 3.5 m/s^2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e., down the slope).
