A 1750kg car starts at the bottom of a 20m tall hill traveling at 15 m/s. During the trip up the hill, air resistance does -50 kJ of work on the car, and friction does an additional -120 kJ of work on the car. What is the minimum amount of work the engine must do in order for the car to reach the top of the hill?

A car of mass 1100 kg starts from rest at sea level and climbs a hill of height 50.0 m. At the top of the hill, the car has a speed of 25.0 m/s, and at this instant, the driver shuts off the engine of the car. The car then coasts down the other side of the hill to height of 15.0 m above sea level. Assume that friction and air resistance are negligibly small. a) (6 pts) How much...

a 1750kg car is parked at the top of a hill with an incline of 12 degrees. Its brakes fail and the car starts rolling down the hill. a) how long will it take for the car to travel 200m and reach the bottom of the hill? (the coefficient of rolling friction between the tires and the road is 0.10) b) what will be its velocity at the bottom?

7. A 1300 kg car drives up a 17 m high hill (the elevation of the hill is 17 meters). During the drive two nonconservative forces do work on the car: the force of friction and the force generated by the car’s engine. The work done by friction adds 331 kJ to the internal energy. The work done by the engine is 634 kJ. (a) What is the change in the car’s kinetic energy? (b) If the car started up...

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.

Wiring problem. In the elevator shaft of a tall building, there are 11 identical electrical wires of finite resistance running from the top of the shaft to the bottom. An electrician needs to determine which wires at the bottom correspond to which wires at the top in order to repair the elevator. One battery and one ammeter are available, and the electrician can connect and disconnect any number of wires at either end. (a) If the electrician starts at the...
