The 1930 kg cable car shown in the figure descends a 200-m-high hill. In addition to its brakes, the cable car controls its speed by pulling an 1760 kg counterweight up the other side of the hill. The rolling friction of both the cable car and the counterweight are negligible. (Figure 1) Part A How much braking force does the cable car need to descend at constant speed?

The figure below shows two blocks connected to each other by a light cable that passes over a pulley with negligible friction. The block of mass m1 = 4.50 kg lies on a horizontal table with negligible friction, while the block of mass m2 = 11.2 kg hangs vertically. (a) What is the magnitude of the acceleration of each block (in m/s2)? (Here, a1 is the acceleration of m1,and a2 is the acceleration of m2.) a1 = m/s2 a2 =...

A 3-kg toy car sits at the highest point of a 13-meter-high hill. The car begins to roll down the slope from rest. Assuming the car coasts freely, without any friction or air resistance, what is the car's speed at each of the indicated points? Use for the acceleration due to gravity, g - 9.80 m/s* Note: the diagram below is NOT to scale. Car's speed Car's speed Number Number m/s m/s 13 m r's speed Number 2 m 6...

The century-old ascensores in Valparaiso, Chile, are small cable cars that go up and down the steep hillsides. As the figure(Figure_1) shows, one car ascends as the other descends. The cars use a two-cable arrangement to compensate for friction; one cable passing around a large pulley connects the cars, the second is pulled by a small motor. Suppose the mass of both cars (with passengers) is 1700 kg, the coefficient of rolling friction is 3.0 times 10^-2, and the cars...

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.

The figure shows a section of a cable-car system. The maximum permissible mass of each car with occupants is 2600 kg. The cars, riding on a support cable, are pulled by a second cable attached to the support tower on each car. Assume that the cables are taut and inclined at angle 0 33°. What is the difference in tension between adjacent sections of puli cable the cars are at the maximum permissible mass and are being accelerated up the...

A 1343 kg car pulls a 415 kg trailer. The car exerts a 3389 N horizontal force against the ground in order to accelerate. Both the car and trailer feel a retarding friction force of 606 N opposing their motion. (a) What is their acceleration? m/s^2 (b) What is the tension in the cable connecting them? N
