The speed of a car increases uniformly with time from 36 km/h at A to 90 km/h at B during 17 seconds. The radius of curvature of the hump at A is 43 m. If the magnitude of the total acceleration of the mass center of the car is the same at B as at A, compute the radius of curvature ρB of the dip in the road at B. The mass center of the car is 0.64 m from the road. Assume ρA = 43 m, h = 0.64 m.

The speed of a car increases uniformly with time from 51 km/h at A to 103 km/h at B during 16 seconds. The radius of curvature of the hump at A is 36 m. If the magnitude of the total acceleration of the mass center of the car is the same at B as at A, compute the radius of curvature ρB of the dip in the road at B. The mass center of the car is 0.73 m from the road. Assume ρA = 36 m, h = 0.73 m. Answer: ρB = m

A radio controlled car, with a mass of 3.0 kg, travels counterclockwise around the curved path shown (viewed from above, gravity is directed into the paper). The radius of curvature of the path is 2.0 m. When at the top of the curve (shown) the speed of the car is 2 m/s and it is slowing down with aT = −2.1 m/s2. The car is not slipping. a. What is the frictional force vector that the ground is applying to the car at the point shown? (Express the force in terms of i and j unit vectors.) b. What is the force that the ground is applying to the car in the z-direction (out of the paper)? c. What is the magnitude of the total force that the ground is applying to the car? d. What is the minimum static coefficient of friction such that the car would not slip at the time shown?

Car A is travelling along a straight line with a velocity of 100 km/h. Car B travels at a speed of 50 km/h along a circular path with a radius of curvature of 20 m. As shown in Figure Q3, the speed of car A is increasing at a rate of 20 km/h2 and the speed of car B is reducing at a rate of 10 km/h2. Fig. Q3 Diagram of the two-car problem.
