At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 2.72 m/s, and an 82.0-kg person feels a 276-N force pressing against his back. What is the radius of a chamber?
4. Sue whirls a yo-yo above her head in a horizontal circle. The yo-yo has a mass of 0.20 kg and is attached to a string 0.80 m long. Ignore the effect of gravity. (a) If the tension in the string is 5.0 N what will be the resulting speed of the yo-yo? (b) Determine the resulting period of the yo-yo’s revolution.
A toy aircraft (without an engine) is attached to the end of a 20 cm long weightless cable. A person holding the other end of the cable starts to spin the cable so that the aircraft starts to fly in a circular path on a horizontal plane. Mass of the aircraft is 125 g. (a) If the spinning cable along with the aircraft moves in a horizontal plane parallel to the ground as the plane reaches a uniform speed of 10 m/s, what is the tension on the cable? (b) If the person spins the cable at a lower speed while holding their end of the cable in the same place as before, the aircraft will now rotate in a horizontal plane closer to the ground than before (i.e. the cable will no longer stay horizontal to the ground). Find the Tension of the cable when the plane is moving at a speed of 5 m/s. (c) Find the angle between the cable and the horizontal plane, for the case described in part (c).
A motorist travels along a vertical circle with a diameter of 10.0 m. After one successful revolution, he notices that his speed at the bottom of the pathway is 6.50 m/s. The mass of the motorists is 70.0 kg. What apparent weight would he feel?
Your roommate is working on his bicycle and has the bike upside down. He spins the 56.0 cmcm -diameter wheel, and you notice that a pebble stuck in the tread goes by three times every second. What is the pebble's acceleration? Express your answer with the appropriate units.
A Ferris wheel has radius of 4.8 m and makes one revolution in 7.4 seconds. A person weighing 686 N is sitting on one of the benches attached at the rim of the wheel. What is the apparent weight (that is, the normal force exerted on her by the bench) of the person as she passes through the highest point of her motion?
A 5 kg mass is attached to a massless string and is being rotated in a horizontal circle. The length of the string is 0.5 m and the mass has a tangential velocity of 10 m/s. Find the tension in the string.
A 16.1 kg mass is connected to a nail on a frictionless table by a massless string 2.9 m long. There is no appreciable friction between the nail and the string. If the tension in the string is 96.5 N while the mass moves in a uniform circle on the table, how long does it take for the mass to make one complete revolution in seconds?
Children playing pirates have suspended a uniform wooden plank with mass M = 13.4 kg, length ℓ = 2.40 m, and angle θ = 35.0°, as shown in the figure. Sophia, with a mass of m = 21.6 kg, is made to "walk the plank" and is d = 1.5 m from reaching the end of the plank. What is the tension acting on the rope at the end (i.e value of F3)?
An object of mass 8.25 kg is travelling in a horizontal circle on a frictionless surface. It is attached to a rope that is 0.987 m long and has a tension of 16.9 N. Calculate the period of the uniform circular motion.
The cable cars in San Francisco are pulled along their tracks by an underground steel cable that moves along at 9.5 mph. The cable is driven by large motors at a central power station and extends, via an intricate pulley arrangement, for several miles beneath the city streets. The length of a cable stretches by up to 100 ft during its lifetime. To keep the tension constant, the cable passes around a 1.5-m-diameter "tensioning pulley" that rolls back and forth on rails, as shown in ( Figure 1). A m = 2000 kg block is attached to the tensioning pulley's cart, via a rope and pulley, and is suspended in a deep hole. m T = 1.5 m Cable Rail Part A What is the tension in the car's cable? Express your answer with the appropriate units.
