here,
the steady speed of train , v = 0.17 m/s
the radius ,r = 0.329 m
the angular speed , w = v/r
w = 0.17 /0.329 rad/s
w = 0.52 rad/s
the angular speed is 0.52 rad/s
A track is mounted on a large wheel that is free to turn with negligible friction...
A 250 g toy car is placed on a narrow 70cm--diameter trackwith wheel grooves that keep the car going in a circle. The 1.4kg track is free to turn on a frictionless, vertical axis. The spokes have negligible mass. Afterthe car's switch is turned on, it soon reaches a steady speed of 0.80 m/s relative to the track.
The wheel consists of a 2.6-kg rim of 420-mm radius with hub and spokes of negligible mass. The wheel is mounted on the 3.7-kg yoke OA with mass center at G and with a radius of gyration about O of 495 mm. If the assembly is released from rest in the horizontal position shown and if the wheel rolls on the circular surface without slipping, compute the velocity of point A when it reaches A'. Answer: vA = m/s 420...
A bicycle wheel of mass M (assumed to be concentrated at its rim) and radius R is mounted horizontally so it may turn without friction on a vertical axle. A dart of mass mo is thrown with velocity vo as shown above and sticks in the tire. a. If the wheel is initially at rest, find its angular velocity co after the dart strikes b. In terms of the given quantities, determine the ratio: final kinetic energy of the system initial kinetic energy of...
The wheel consists of a 2.5-kg rim of radius r = 215 mm with hub and spokes of negligible mass. The wheel is mounted on the 3.0-kg yoke OA with mass center at G and with a radius of gyration about 0 of 350 mm. If the assembly is released from rest in the horizontal position shown and if the wheel rolls on the circular surface without slipping, compute the velocity of point A when it reaches A'. Assume d...
A hoop of mass M = 2 kg and radius R = 0.4 m rolls without slipping down a hill, as shown in the figure. The lack of slipping means that when the center of mass of the hoop has speed v, the tangential speed of the hoop relative to the center of mass is also equal to VCM, since in that case the instantaneous speed is zero for the part of the hoop that is in contact with the...
A hoop of mass M = 3 kg and radius R = 0.4 m rolls without slipping down a hill, as shown in the figure. The lack of slipping means that when the center of mass of the hoop has speed v, the tangential speed of the hoop relative to the center of mass is also equal to vCM, since in that case the instantaneous speed is zero for the part of the hoop that is in contact with the...
12. (5 points) A speedway turn, with radius of curvature R, is banked at an angle 0 above the horizontal. If the track surface is ice-free and R 450.0 m, there is a coefficient of friction ,,-0.65 between the tires and the track, and the 3-450°, what are the m n speeds at which this turn can be taken? 13. (10 points) Rolling down problem. Start from rest Final speed A spherical shell of mass M-0.5 kg and radius R-0.5m...
13. Points A wheel is made up of a uniform thin rim (hollow cylinder) of mass 2m kg and 6 thin uniform spokes each of mass m kg and length L = 0.5 meters. The wheel is given an initial translational speed Vo = 10.0 m/s and launches vertically from the top of a quarterpipe of height h -5.00 meters. The wheel rolls without slipping along the ramp, and air resistance is negligible. a) Find the moment of intertia about...
An unpowered railroad car of mass 200kg rolls with negligible friction on a horizontal track with a speed of 10 m/s. A 100-kg hobo drops straight down a distance of 4.0 m, from an overpass and lands in the car. How fast will the car be moving after this happens? please write on piece paper Also draw helps me to understand
1. A hoop of wire in the shape of a circle of radius RAs mounted vertically and rotates at constant angular speed w about a vertical axis through its center. A bead with the mass of m moves smoothly on the wire. Find the equilibrium positions and discuss their Stabili when we neglect the damping effect on the bead motion. Consider two cases, e the hoop is rotating slowly9/R), (u 9/R). Here g is the gravity. n. ) when the...
