5. A 1000-kg car is at the top of a hill as shown, where its elevation above the bottom of the hill is 120 m. a. What is its gravitational potential energy? 120 m b. If the cart starts from rest and rolls down the hill with negligible friction and air resistance, what will its kinetic energy be when it reaches the bottom? c. What will be its speed when it reaches the bottom? Suppose instead that there is noticeable...

Problem # 4 The 3000 kg cable car shown in figure descends a 200 m-high hill. In addition to its brakes, the cable car controls its speed by pulling a 2500 kg counterweight up the other side of the hill. The rolling friction of both the cable car and the counterweight are negligible. Counterweight 200 m 25° 35 A. Draw the free body diagrams of cable car (call it m,) and the counterweight (call it m2) mass. Draw component diagrams....

A 3900 kg car is parked at the top of an 8.7 m long driveway that is sloped at 17? with the horizontal. The parking brake fails. If an average friction force of 4200 N im- pedes the motion, find the speed of the car at the bottom of the driveway. The acceleration of gravity is 9.8 m/s2 . Starting from rest, a 10.0 kg suitcase slides 3.00 m down a frictionless ramp inclined at 31.0? from the floor. The...

A 1250 kg car drives up a hill that is 16.2 m high. During the drive, two nonconservative forces do work on the car: (i) the force of friction, and (ii) the force generated by the car's engine. The work done by friction is -2.91 times 10^5 J; the work done by the engine is 6.64 times 10^5 J. Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.

1. Once again we have a skier on an inclined plane. The skier has mass M and starts from rest. Her speed at the bottom of the slope is 12.0 meters/second. The hill is inclined 30 degrees from the horizontal and the length of the slope is 100.0 meters. Use the law of conservation of energy to determine her final speed and write that number down here: What could account for the difference in your...

Vo 5) h 200 m A driver coasts down a hill 200 m high with initial speed vo 40 m/s. The road has friction that results in a negative work -1.7 x 10 J. The effect of this is that the total initial energy is reduced by this amount by the time the car reaches the bottom of the hill. Calculate the speed of the car when it reaches the bottom of the hill. The mass of driver and passenger...
