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 to drift freely down the hill. The car descends a height of .3 km in a distance of 6.4 km before leveling out, with average resistive force acting on the car 500 N. Estimate the acceleration of the car down the incline and the speed of the car at the bottom of the incline.

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...

A car that would normally weigh 9800 N (mass is 1000kg) drives over a hilltop that has a radius of curvature of 120 m at the top of the hill. At what speed would the car be traveling at the top of the hill such that the normal force from the road is only 500 N? Friction is negligible

A car travels down a straight country road that leads over hills and through valleys. On one particular stretch of road, the car encounters a hill that can be approximated as the top of a circle with a radius rh = 105 m. Later, the car comes to a dip with a radius of curvature rd = 75 m. Assume that the car maintains a constant speed of v = 23 m/s as it goes over the hill and through...

The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...
