Question

Show units, check the ones I did and show workj for all parts

A 1.535-kg car is moving down a road with a slope (grade) of 10% at a constant speed of 13 nVs. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. down the slope)? A 1.576-kg car is moving down a road with a slope (grade) of 11% while slowing down at a rate of 3.6 rrv'sA2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. down the slope)? A 1.729-kg car is moving down a road with a slope (grade) of 23% while speeding up at a rate of 1.9 rrv'sA2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. down the slope)? A 1.952-kg car is moving down a road with a slope (grade) of 10% while speeding up at a rate of 3.2 rrv'sA2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. down the slope)? A 2.282-kg car is moving up a road with a slope (grade) of 10% at a constant speed of 12 rVs. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. up the slope)? F. A 1.712-kg car is moving up a road with a slope (grade) of 38% while slowing down at a rate of 1.5 nv'sA2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. up the slope)? car is moving up a road with a slope (grade) of 11% while slowing down at a rate of 3.3 nv'sA2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. up the slope)? H. A 1.463-kg car is moving up a road with a slope (grade) of 31% while speeding up at a rate of 3.4 nVsA2. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. up the slope)?
