A road heading due east passes over a small hill. You drive a car of mass mat constant speed over the top of the hill, where the shape of the roadway is well approximated as an arc of a circle with radius R. Sensors have been placed on the road surface there to measure the downward force that cars exert on the surface at various speeds. The table gives values of this force versus speed for your car is shown in the table below. Treat the car as a particle.

Speed (m/s)	6.00	8.00	10.0	12.0	14.0	16.0
Force (N)	8100	7690	7050	6100	5200	4200

Select a way to represent the data from figure as a straight line. You might need to raise the speed, the force, or both to some power.

Calculate the maximum acceleration of a car with four wheel drive that is heading up a 8° slope (one that makes an angle of 8° with the horizontal) under the following road conditions. Assume that the static coefficient of friction is involved--that is, the tires are not allowed to slip during the acceleration. (a) on dry concrete ________m/s2 (b) on wet concrete _________ m/s2 (c) on ice, assuming that µs = 0.100, the same as for shoes on ice _________m/s2

You push a box of mass 19.1 kg with your car up to an icy hill slope of irregular shape to a height 5.9 m. The box has a speed 12.9 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before sliding into a box larger box of mass 13 kg. The boxes then fall off a sheer cliff together to the...

You push a box of mass 17.4 kg with your car up to an icy hill slope of irregular shape to a height 5.1 m. The box has a speed 11.8 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before elastically colliding with a smaller box of mass 12 kg. The boxes then fall off a sheer cliff individually to the...

A 1150 kg car drives up a hill that is 15.7 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 −2.91×105 J ; the work done by the engine is 6.74×105 J . Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.

A car moving due east at 6 m/s collides at the intersection with an identical car. If the entangled wreckage moves at 5.5 m/s at 22 degrees north of east after the collision, what was the velocity and direction of the second car immediately before the collision? The entangled wreckage slides along the horizontal road leaving skid marks. If the coefficient of friction between the entangled wreckage and the road is 0.34, how long are the skid marks?

A plane with a speed of 800.0 km/hr due east passes directly above a train traveling due southeast at 100.0 km/hr on a straight level road. The altitude of the aircraft is 10.0 km. How fast is the distance between the plane and the train increasing 45 s after the aircraft passes directly above the train?

A car with a mass of 980 kg is initially traveling east toward an intersection with a speed of vc = 19.6 m/s and a 1500 kg pickup is traveling north toward the same intersection. The car and truck collide at the intersection and stick together. After the collision, the wreckage (car and truck) moves off in a direction of 35.0° above the x-axis. Determine the initial speed of the truck and the final speed of the wreckage. a. initial...
