a 150g marble rolling down a marble track is going through a 10 cm tall loop. Assuming the track is perfectly efficient and the marble experiences circular motion in the loop: what is the minimum magnitude of the normal force provided by the loop to manta in circular motion at the top of the loop? How high should the hill before the loop be to ensure the marble can travel through the whole loop?
For the normal force in the drawing to have the same magnitude at all points on the vertical track, the stunt driver must adjust the speed to be different at different points. Suppose, for example, that the track has a radius of 2.24 m and that the driver goes past point 1 at the bottom with a speed of 28.3 m/s. What speed must she have at point 3, so that the normal force at the top has the same magnitude as it did at the bottom?
A roller coaster goes around a vertical loop that has a diameter of 40 m. What is the minimum speed that the roller coaster car must go at the top of the loop to stay on track? (the total mass is 600 kg) (
A small object of mass 0.20 kg is whirled in a horizontal circle at the end of the 1 m long cord. What is the highest speed that the object can have if the cord can sustain a maximum force of 4 newtons without breaking?
A metallic box begins at rest at point 1 at a height of 5R, where R is the radius of the circular part of the track. The box slides down the frictionless track and around the loop. If the box has a gravitational weight of 80 N, what is the magnitude of the normal force acting on the box at point 2?
Just before entering the tunnel, you notice the sign that says you must "use the tunnel with your bicycle on foot" but it is too late and you are descending through the tunnel with an initial speed of 6.6 km / h. The tunnel has a semicircular ramp with radius R = 6.3 m, and its mass combined with the mass of the bicycle is 60.3 kg. a) Find the velocity at the bottom of the curve, point 2, for when the friction force is negligible.
As a roller coaster crosses the top of a 50 m diameter loop the loop, it’s apparent weight is the same as its true weight. What is the cars speed at the top?
A roller coaster consists of a car attached underneath a thin rail in the shape shown in the figure. The rail loops are circular and there is no friction between the carriage and the rail. The car is represented by the red block and the gray dotted line is a visualization of a part of the path that the car follows. (a) What is the minimum speed v_0 that the car must have at the bottom of the loop system for its centripetal acceleration to satisfy a_c = g at the top of the large loop? Write your answer in terms of R, g (b) Will that speed be the same for the condition a_c = g to hold at the top of the small loop? Show why?
Lola can do a loop-the-loop on a skateboard of radius 4.9 m. What is the minimum speed needed for Lola to remain on the track while upside down?
A roller coaster at the Six Flags Great America amusement park in Gurnee, Illinois, incorporates some clever design technology and some basic physics. Each vertical loop, instead of being circular, is shaped like a teardrop (Fig. P5.22). The cars ride on the inside of the loop at the top, and the speeds are fast enough to ensure the cars remain on the track. The biggest loop is 40.0 in high. Suppose the speed at the top of the loop is 13.0 m/s and the corresponding centripetal acceleration of the riders is 2g. (a) What is the radius of the arc of the teardrop at the top? (b) If the total mass of a car plus the riders is M, what force does the rail exert on the car at the top? (c) Suppose the roller coaster had a circular loop of radius 20.0 m. If the care have the same speed, 13.0 m/s at the top, what is the centripetal acceleration of the riders at the top? (d) Comment on the normal force at the top in the situation described in part (c) and on the advantages of having teardrop-shaped loops.
A makeshift sign hangs by a wire that is extended over an ideal pulley and is wrapped around a large potted plant on the roof as shown in Figure P6.10. When first set up by the shopkeeper on a sunny and dry day, the sign and the pot are in equilibrium. Is it possible that the sign falls to the ground during a rainstorm while still remaining connected to the pot? What would have to be true for that to be possible? FIGURE P6.10 Problems 10 and 11.
