- 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 74.0 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?Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holly Compton designed a speed bump (called the "Holly hump") and had it installed. Suppose a 1 800-kg car passes over a hump in a roadway that follows the arc of a circle of radius 19.6 m (a) If the car travels at 25.0 km/h what force does the road exert on the car as the car passes the highest point of the hump? magnitude N direction (b) What is the maximum speed the car can have without losing contact with the road as it passes this highest point?A small car with mass 0.650 kg travels at constant speed on the inside of a track that is a vertical circle with radius 5.00 m. a. If the normal force exerted by the track on the car when it is at the top of the track (point B) is 6.00 N, what is the normal force on the car when it is at the bottom of the track (point A)?
- A roller-coaster car of mass 309 kg (including passengers) travels around a horizontal curve of radius 35.2 m. Its speed is 21.3 m/s. a. What is the magnitude of the total force exerted on the car by the track? answer in N b. What is the direction of the total force exerted on the car by the track? Enter a positive angle if the direction is above horizontal and a negative answer if the direction is below horizontal. answer in degrees c. If the track is frictionless, then what banking angle would ensure that the car does not slide off of the track? (The banking angle is the angle between the direction normal to the track and the vertical.) answer in degreesSquare A and square B have equal massess, 0.260 kg. Additionally, a smaller square with a mass of 0.010 kg is situated at point P. Find the magnitude and direction for questions. net gravitational force acting on the 0.010 kg square at point P? net gravitational force acting on the 0.260 kg square at point A? net gravitational force acting on the 0.260 kg square at point B?You are in a carnival ride that consists of a circular room that spins around its center. You stand against the wall at the edge of the room. The room spins at a constant rate of one revolution every 5 seconds, and the room has a radius of 5 m. Your mass is 70 kg. After the room reaches it final speed, the floor drops out from beneath you, yet you remain stuck to the wall. What is the magnitude of the normal force exerted on you by the wall, and at what rate (power) does the normal force perform work on you? (Please explain the power that the normal force does work in detail.)
- A stone that is connected to a string is being rotated horizontally. The stone completes one full circle every second; and the magnitude of the tension in the string is F-. What happens to the tension in the string if the stone speeds up such that it goes around the circle twice every second while the radius stays the same. O The magnitude of the tension increases to twice its original value. O The magnitude of the tension increases to four times its original value. O The magnitude of the tension reduces to one-fourth of its original value. O The magnitude of the tension is unchanged. O The magnitude of the tension reduces to half of its original value.A 15.0 kgkg sphere is at the origin and a 5.00 kgkg sphere is at x� = 20 cmcm.
