A car drives up an incline. The
force diagram of the car is shown in the figure. The force F is
generated by the engine. The Force N is the normal force on the
car. The force Ffriction is the kinetic friction on the car. The
Force mg is the gravitational force on the car. For each of the
four forces on the car, draw a diagram including only that force
vector and the car’s displacement vector. Determine whether the
work done by that force is positive, zero, or negative.

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.

A car has an initial speed of 118 km/h and climbs up an incline with its engine DISENGAGED (no engine force). DON"T use scientific notation. Angle is 33 degrees. (a) If work done by friction is negligible, How high (the h in the figure) a hill can the car coast up (engine disengaged) before coming to a stop? (b) If, in actuality, a 700-kg car with an initial speed of 118 km/h is observed to coast up a hill to...

A car drives up a straight incline of 4.8 km in length and .3 km in height. The car moves up the incline at a steady speed of 16 m s^-1, with friction force being 500 N and total weight of car and driver being 12000 N. From the top of the incline, the road continues downwards in a straight line. At the point where the road starts to go downwards, the driver stops the engine and allows the car...

Jordan uses a rope to pull a heavy crate up an incline. The incline has non-negligible friction. Identify all of the forces acting on the crate while Jordan is pulling, and state whether they are doing positive work, negative work, or no work. (If friction is one of your forces, specify whether is kinetic or static.)

А D z Problem 3. Work done by gravity and change in gravitational potential energy In problem the box was moving in a horizontal direction, and therefore no work was done by gravity. Here, we will analyze a situation where the force of gravity has some component that points along the direction of the displacement, and therefore there is non-zero work done by gravity on the system of interest Consider a box of mass 10 kg, initially at rest, which...

At an amusement park, a car of mass m rolls without friction around a track as shown. The car starts from rest at point A, a height h = 3R above the bottom of the loop (R is the radius of the loop). Treat the car as a point-like particle. (a) Draw the free body diagram for the car and find the car’s kinetic energy and normal force acting on the car at the top of the loop (point B)....
