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...

In the figure, a car is driven at constant speed over a circular hill and then into a circular valley with the same radius. At the top of the hill, the normal force on the driver from the car seat is 0. The driver's mass is 56.0 kg. What is the magnitude of the normal force on the driver from the seat when the car passes through the bottom of the valley? Raclius Raclius Units Number

3. A car with mass m travels over a hill with a radius of curvature of r at a speed of 15 m/s. What is the normal force on the car when the car is at the top of the hill? (6 pts) the car has a mass of 1200 Kilograms and the radius of curvature is 25 meters 4. A student with a mass of m rides a roller coaster with a loop with a radius of curvature of...

1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c) the centripetal force acting on the car, (d) the tangential acceleration of the car, and (e) the magnitude of the...

A car drives over a rounded hill. A) What is the fastest the car can go, in m/s, without the tires coming off of the road? B) If the mass of the car is 1500 kg, what is the net force on the car when it is at the top of the hill when it travels at a speed of 5 m/s?

Problem 3 The mass of the trailer in the figure is 750 kg and is being hitched by a car linked to the trailer at point P. The road is horizontal and the two identical tires can be considered as one, with a single normal reaction and negligible frictional force; the air resistance will also be neglected. (a) Compute the normal force in the tires and the vertical force at point P, when the speed is constant. (b) When the...

Brake or turn? Figure 6-45 depicts an overhead view of
a car's path as the car travels toward a wall. Assume that the
driver begins to brake the car when the distance to the wall is
d = 109 m, and take the car's mass as m = 1430
kg, its initial speed as v0 = 37.0 m/s, and the
coefficient of static friction as μs = 0.530.
Assume that the car's weight is distributed evenly on the four
wheels,...
