Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holy Compton designed a speed bump (called the Holly Humo) and had it installed. Suppose 1000-kg car passes over a hump In a roadway that follows the art of a circle of radius 18.4 m as in the figure below (a) of the car travels at 28.8 km/h what force does the road exert on the car as the carpasses the highest point of the hump? magnitude direction (b) What...

Question 3 20 pts When crossing an intersection, a motorcyclist encounters the slight bump or crown caused by the intersecting road. If the crest of the bump has a radius of curvature P-59.03 ft, determine the maximum constant speed at which he can travel without leaving the surface of the road. Neglect the size of the motorcycle and rider in the calculation. The rider and his motorcycle have a total weight of 471 lb. Give your solution in mph (miles...

009 (part 1 of 2) 10.0 points A civil engineer is asked to design a curved section of roadway that meets the following conditions: With ice on the road, when the coefficient of static friction between the road and rubber is 0.24, a car at rest must not slide into the ditch and a car traveling less than 70 km/h must not skid to the outside of the curve. The acceleration of gravity is 9.81 m/s2. At what angle should...

Problem 3 (30 points) Three cars are driving at 15 m/s along the road shown in Fig 2. Car B is at the bottom of a hill and car C is at the top. Both hills have a 200 m radius of curvature. Suppose each car suddenly brakes hard and starts to skid. a) What is the tangential acceleration (i.e, the acceleration parallel to the road) of each car? Assume μ 1.0. b) What is the centripetal (radial) acceleration of...

3. A car is driving at a speed of 20 m/sec on a circular horizontal flat (unbanked) road of radius 200 m. (a) What minimum coefficient of static friction will permit the car to follow the circular path without skidding? (b) If the road had a radius of 32 m, what is the maximum speed of the car without skidding? (c) If the road was banked (not flat), could the car go faster? Explain your answer Possibly (but not necessarily)...
