Suppose a 2,000-kg car passes over a bump in a roadway that follows the arc of a circle of radius 21.0 m as in the figure shown below. (a) What force does the road exert on the car as the car passes the highest point of the bump if the car travels at 9.50 m/s? (Neglect any friction that may occur.) kN magnitude direction -Select--- (b) What is the maximum speed the car can have without losing contact with the road as it passes this highest point? m/s

25) In a movie stunt, a car leaves an inclined ramp with a speed of 32.0 m/s. The car's mass is 1050 kg and its velocity is 29.0 m/s at the peak of its flight. How high in the air (relative to the location where it left the ramp) is the car at the peak of its flight? Assume that there is no air problem can be done using Kinematics too. g although the v = 32 m/s h = ? m = 1050 kg 0.01 lo ribar a and boa pugi oq anoiudover '01

A string can support a stationary hanging load of mass 25 kg before breaking. a) Calculate the maximum tension that the string can support. b) Suppose one end of the string is attached to an object of mass m = 3 kg, while the other end is fixed to the center of a frictionless table as shown in the figure. When given an initial speed, the object moves along a horizontal circle of radius R = 0.8 m. Calculate the maximum speed the object can have before the string breaks.
