A900-kg car initially at rest rolls 50 m down a hill inclined at an angle of 5.0°. a 400-n effective friction force opposes its motion.
a. what distance will it travel on a similar horizontal surface (assume the friction force is the same) at the bottom of the hill?
b. if the friction force remains the same will the distance decrease or increase if the car's mass is 1800 kg?
o will decrease
o will increase
o will remain the same
