A 95.5 kN car is traveling at 70.9 mph when the driver decides to exit the freeway by going up a ramp. After coasting 3.90 x 10² m along the exit ramp, the car's speed is 28.1 mph and it is h = 13.7 m above the freeway. What is the magnitude of the average drag force exerted on the car?

Bank robbers have pushed a 1000 kg safe to a third-story floor-toceiling window. They plan to break the window and lower the safe 10.0 m to their truck. Not being too clever, they stack up 500 kg of furniture, tie a rope between the safe and the furniture, and place the rope over a pulley. Then they push the safe out of the window. The coefficient of kinetic friction between the furniture and the floor is 0.5. The rope would break if the force on it exceeds 5000 N. a) Does the rope break? b) What is the acceleration of the safe? c) What is the safe’s speed when it hits the truck?

A 3.00-kg block is sent up a ramp inclined at an angle 0 = 27.0° from the horizontal. It is given an initial velocity vo = 15.0 m/s up the ramp. Between the block and the ramp, the coefficient of kinetic friction is µ = 0.30 and the coefficient of static friction is µ, = 0.80. What distance D along the ramp's surface does the block travel before it comes to a stop? D =

A skier starts from rest at the top of a hill that is inclined at 11.0° with respect to the horizontal. The hillside is 220 m long, and the coefficient of friction between snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier glide along the horizontal portion of the snow before coming to rest?
