Why is the following situation impossible? The object of mass m = 4.00 kg in Figure P5.18 is attached to a vertical rod by two strings of length = 2.00 m. The strings are attached to the rod at points a distance d = 3.00 m apart. The object rotates in a horizontal circle at a constant speed of v = 3.00 m/s, and the strings remain taut. The rod rotates along with the object so that the strings do not wrap on to the rod. What If? Could this situation be possible on another planet?
Why is the following situation impossible? A mischievous child goes to an amusement park with his family. On one ride, after a severe scolding from his mother, he slips out of his seat and climbs to the top of the rides structure, which is shaped like a cone with its axis vertical and its sloped sides making an angle of = 20.0 with the horizontal as shown in Figure P6.32. This part of the structure rotates about the vertical central axis when the ride operates. The child sits on the sloped surface at a point d = 5.32 m down the sloped side from the center of the cone and pouts. The coefficient of static friction between the boy and the cone is 0.700. The ride operator does not notice that the child has slipped away from his seat and so continues to operate the ride. As a result, the sitting, pouting boy rotates in a circular path at a speed of 3.75 m/s. Figure P6.32
An air puck of mass m1 = 0.25 kg is tied to a siring and allowed to revolve in a circle of radius R = 1.0 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of m2 = 1.0 kg is tied to it (Fig. P7.27). The suspended mass remains in equilibrium while the puck on the tabletop revolves, (a) What is the tension in the string? (b) What is the horizontal force acting on the puck? (c) What is the speed of the puck? Figure P7.27
In an amusement park ride called ‘The Roundup’, passengers stand inside a 18-m diameter rotating ring. After thering has acquired its final speed of 14 rpm’s, it tilts into a vertical plane. Whatweight does the rider feel at the top and bottomif they have a weight of 830 N?
In 1956, Frank Lloyd Wright proposed the construction of a mile-high building in Chicago. Suppose the building had been constructed. Ignoring Earth’s rotation, find the change in your weight if you were to ride an elevator from the street level, where you weigh 600 N, to the top of the building.
In an amusement park ride called The Roundup, passengers stand inside a 19.0 m -diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane, suppose the ring rotates once every 5.1s. If a rider's mass is 56kg, with how much force does the ring push on her at the top of the ride and at the bottom of the ride? What is the longest rotation period of the wheel that will prevent the riders from falling off at the top?
It has been suggested that rotating cylinders about 15.0 mi long and 5.89 mi in diameter be placed in space and used as colonies. What angular speed must such a cylinder have so that the centripetal acceleration at its surface equals the free-fall acceleration on Earth? = rad/s
A tree of 35 m length and a mass of 500 kg is chopped down. Consider the situation when thetree (full cylinder shape) is about to hit the ground. Which force is driving the rotation? Whatis the track acceleration of the bottom, in the middle and at the top end of the tree?
A 50.0-kg child stands at the rim of a merry-go-round of radius 2.00 m, rotating with an angular speed of 3.00 rad/s. (a) What is the child’s centripetal acceleration? (Ans : 18.0 m/s2) (b) What is the minimum force between her feet and the floor of the carousel that is required to keep her in the circular path? (Ans : 900 N) (c) What minimum coefficient of static friction is required? Is the answer you found reasonable? In other words, is she likely to stay on the merry-go-round? (Ans : 1.84)
A 2.97 gram fine is placed 0.10 m from the centre of a rotating disc. The coefficient of static friction between the fine and the disc is 0.28. What is the maximum speed of rotation, ( at the position of the dime), that the disc can rotate without sliding off?
Unlike a roller coaster, the seats in a Ferris wheel swivel so that the rider is always seated upright. An 80-ft-diameter Ferris wheel rotates once every 24 s. What is the apparent weight of a 70 kg passenger at (a) the lowest point of the circle and (b) the highest point?
1) A boy releases his 2.0 kg toy, from rest, at the top of a sliding-pond inclined at 20o above the horizontal. What will the toy's speed be after sliding 4.0 m along the sliding-pond? The coefficient of kinetic friction is 0.20. 2) A race car, traveling at a constant speed of 50 m/s, drives around a circular track of radius 250 m. What angular acceleration does it experience?
