Question

A child of mass 45 kg stands at the edge of a
merry-go-round of mass 120 kg and radius
2.6 m, and both are initially at rest. The child
then walks along the edge of the merry-go-
round until she reaches a point opposite her
starting point as measured on the ground (
point B in the figure below). How far does the
child walk as measured relative to the merry -
go-round? Start Finish

Consider two cylindrical objects of the same mass and radius. Object A is a solid cylinder, whereas object B is a hollow cylinder. 1) How fast, in meters per second, is object A moving at the end of the ramp if it's mass is 220 g, it's radius 21 cm, and the height of the beginning of the ramp is 19.5 cm? vA = 2) How fast, in meters per second, is object B moving at the end of the ramp if it rolls down the same ramp? vB =
A coin of mass m and rotates on a circular platform of radius r at the fastest speed possible without the coin sliding off. In this case, the coin makes each revolution in 5.7 seconds (its period). The coin and platform have a coefficient of friction, that is unchanged. If the mass of the coin is increased by a factor of 4, what would be the new period? Give your answer to 1 decimal place
Question 11 On a faraway planet, Marvin ascends a launch tower that is 2300 m high. At this height, he fires a projectile (of mass 4 kg) from point A. His goal is to have the projectile travel around the planet in a nearly circular trajectory and return to point A. At what velocity must he fire the projectile? The radius of the planet Rlanet is 33736 km and its mass is 102.413 ? 1024 kg. Assume: i) you can neglect air resistance and the pull due to any of the planets moons and ii) the projectile?s flight is unobstructed (PUHQ1135) a) O11387.00 m/s b) O14233.00 m/s c) 07116.70 m/s d) 04744.50 m/s

Multiple-Concept Example 7 deals with the concepts that are important in this problem. A penny is placed at the outer edge of a disk (radius= 0.183 m) that rotates about an axis perpendicular to the plane of the disk at its center. The period of the rotation is 1.87 s. Find the minimum coefficient of friction necessary to allow the penny to rotate along with the disk. Hs = Number i Units
In the problems below, “little g” plays a variety of roles. Near the earth’s surface, g has a value of 9.81 m/s2. At other locations g may have different values. Solve these word problems using the data provided below.

In an amusement park ride, a child stands against the wall of a cylindrical room that is then made to rotate. The floor drops downward and the child remains pinned against the wall. If the radius of the room is 2.15 m and the relevant coefficient of friction between the child and the wall is 0.600, with what minimum speed is the child moving if he is to remain pinned against the wall? 07.26 m/s O3.93 m/s O 12.1 m/s 5.93 m/s 9.80 m/s
A circular track has several concentric rings where people can run at their leisure. Phil runs on the outermost track with radius rP while Annie runs on an inner track with radius rA = 0.70 rP. The runners start side by side, along a radial line, and run at the same speed in a counterclockwise direction. How many revolutions has Annie made when Annie's and Phil's velocity vectors point in opposite directions for the first time?
