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

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question
