A motorcycle is traveling up one side of a hill and down the other side. The crest of the hill is a circular arc with a radius of 49.4 m. Determine the maximum speed that the cycle can have while moving over the crest without losing contact with the road.
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 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 drives over the crest of a hill of radius 120m with a speed of 39m/s. Does the car maintain contact with the road? Explain.
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?
Suppose a 1,850-kg car passes over a bump in a roadway that follows the arc of a circle of radius 22.0 m as in the figure shown below. A car traveling to the right over a hump on the road at a velocity vector v. (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 8.30 m/s? (Neglect any friction that may occur.) magnitude__________ kN...
1) A bicyclist is traveling at 25 km/hr when he encounters a 90 m hill. Neglecting road and wind resistance: a) If the hill is going up, what vertical elevation could the cyclist achieve without pedaling? b) If the hill is going down, what speed would the bicyclist achieve without pedaling?
A car is traveling down a hill that makes an angle of 17° with the horizontal. The driver applies her brakes, and the wheels lock so that the car begins to skid. The coefficient of kinetic friction between the tires and the road is μK = 0.53. (a) Find the acceleration of the car. (Take down the ramp to be the positive direction) (b) How long does the car take to skid to a stop if its initial speed is...
A solid, uniform ball rolls without slipping up a hill. At the top of the hill, it is moving horizontally; then it goes over the vertical cliff. Take V = 25.0 m/s and H = 30.0 m . Part A: How far from the foot of the cliff does the ball land? Part B: How fast is it moving just before it lands? Part C: Notice that when the ball lands, it has a larger translational speed than it had...
when it strikes the ground Free-Body Diagram: A pulley system slides down a hill. The hill is tilted up a' an angle O above the horizontal ground, (a) Draw·free-kdy rest if the blocks m and m remain stationary relative to the sliding mass M pulley system. All surfaces are frictionless ulley is massless and frictionless. Mass m is in contact with mass M w the position vs. time graph(s) for all moving masses. when it strikes the ground Free-Body Diagram:...
