- An engineer is trying to determine the speed at which a car can travel around a curved race track without using any friction, Assume the car does not move up or down the incline and completes a horizontal circle. Complete all calculations under these circumstances. Hint: Use the variable m for the mass of the car, it will cancel! number of forces in plane: centripetal force: 340m Are all forces balanced? 160 What is the magnitude of the centripetal acceleration? unit At what speed does the car need to travel? unit finalize check answers cannot be determined (after completing ALL problems) Unit 10: circular motion, challenge Desmos Scientific Online Calculator hp esc HAAR @ #3 2$ & 96A car is moving on a banked curve at a speed v. A car is moving on a circular (radius = R) banked track (banking = B = 10° with respect to the horizontal) at a constant speed, v, in a circular path of radius R. A normal force, n, is exerted on the car from the track. The centripetal force is equal to the total normal force 0000 the radial component of the normal force the vertical component of the normal force none of the aboveCentripetal Force: I'm trying to understand the forces at work in centripital force, i understand that if an object is moving in a circle then their must be a net inward acceleration. So if centripetal force is what is pushing in on the object toward the center of the circle, then what is pushing outward to counteract this force and hold the object in its rotation? Like a tenis ball on a string, if i swing it and it gain an inward force, then as it swings under that logic it would approach my hand. What is pushing it out?
