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
Chapter 06, Problem 049 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 93.0 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? Radius ! Radius l1s...
You're driving your new sports car at 85 mph over the top of a hill that has a radius of curvature of 540 m.
A motorcycle has a constant speed of 25.5 m/s as it passes over the top of a hill whose radius of curvature is 145 m. The mass of the motorcycle and driver is 328 kg. Find the magnitude of (a) the centripetal force and (b) the normal force that acts on the cycle.
A motorcycle has a constant speed of 20.0 m/s as it passes over the top of a hill whose radius of curvature is 102 m. The mass of the motorcycle and driver is 318 kg. Find the magnitude of (a) the centripetal force and (b) the normal force that acts on the cycle.
A 1100 kg car traveling at 20 m/s goes over a hill. At the top, the hill provides an upward normal force of 5600 N. (a) Assuming the hill has a circular profile, find the radius of curvature of the hill. (b) What is the maximum speed the car can go over the hill without ramping the car off the ground?
A car is travelling at the top or a semi-circular hill, and at the top of the hill, it is moving exactly at 32 m/s which is exactly the speed needed to just leave the road/hill. If the same car is travelling over a hill which is one quarter as tall (radius is one quarter), what is the maximum speed, in m/s, it can travel before it just starts to leave the hill?
A road has a hill with a top in the shape of a circular arc of radius 32.0 m. How fast can a car go over the top of the hill without losing contact with the ground?
A car rounds a circular track of radius 950 m. What is the maximum speed the car can be driven if its centripetal acceleration must not exceed 2.8 m/s2? Select one: O A. 51.58 m/s O B. 76.90 m/s O C. 89.14 m/s O D. 121.17 m/s
A car is going along a circular road at a constant speed. The radius of the curve is 290 m, and the car takes 1.7 minutes to complete one round. Calculate its centripetal acceleration in m/s2.
