The figure shows four overhead views of rotating uniform disks that are sliding across a frictionless floor. Three forces, of magnitude F,2F, or 3F, act on each disk, either at the rim, at the center, or halfway between rim and center. The force vectors rotate along with thedisks, and, in the "snapshots" of the figure, point left or right.2F(a)F3F2F 2F(b)(c)(d)Which disks are in equilibrium?

An energetic parent places his 20 kg child on a 5.0 kg cart to which a 2.0-m-long rope is attached. He then holds the end of the rope and spins the cart and child around the circle, keeping the rope parallel to the ground. If the tension in the rope is 100 N, how many revolutions per minute does the cart make? Note: rolling friction between the cart's wheels and the ground is negligible.
An object with mass M slides across a frictionless half-circular slide of radius R. The object is initially held stationary at the top of the slide. The initial height is, hi = R. The mass is released and slides down, around the bottom, and back up the other side. The radius of the slide is R = 5.79 m and the mass of the object is M = 37 kg. When the object is moving up the slide, at an angle θ = 18o from the vertical, what is the normal force on the object?
A semi-cylindrical groove of radius r = 20 cm is made on a horizontal floor. An ant wants to cross the groove. A boy decides to help the ant making a bridge consisting of straight wire segments. But all the wires available are of length l = 38 cm, so the boy rigidly connects two wires at right angle and places the bridge in the groove as shown in the figure. If the ant can crawl up a wire segment at speed v = 0.5 cm/s and down a wire segment at speed 2v, in what minimum time can the ant cross the groove with the help of this bridge?
Chad gets on a roller coaster. Chad and the cart rolls down the frictionless loop with a constant speed of 7.4 m/s. The mass of Chad and the cart is 0.75 kg and the radius of the loop is 0.86 m. Since the cart has a smaller dimension than the loop, the cart can be viewed as a point particle. What is the normal force at the top and bottom points? The magnitude of the gravitational acceleration is 9.8 m/s^2. Draw a free body diagram.
Two satellites are in circular orbits around a planet that has radius Rp = 9.00 x 106 m. One satellite has mass m₁ = 68.0 kg, orbital radius r₁ = 5.00 × 107 m, and orbital speed v₁ = 4800 m/s. The second satellite has mass m₂ = 84.0 kg and orbital radius 12 = 3.00 x 107 m. a. Calculate the orbital speed of the second satellite. b. Calculate the total mechanical energy of both satellites.
You are testing a new amusement park roller coaster with an empty car with a mass of 130 kgkg. One part of the track is a vertical loop with a radius of 12.0 mm. At the bottom of the loop (point A�) the car has a speed of 25.0 m/sm/s and at the top of the loop (point B�) it has speed of 8.00 m/sm/s. As the car rolls from point A� to point B�, how much work is done by friction?
A Stone Age hunter stands on a cliff overlooking a flat plain. He places a 1.0 kg rock in a sling, ties the sling to a 1.0-m-long vine, then swings the rock in a horizontal circle around his head. The plane of the motion is 25 m above the plain below. The tension in the vine increases as the rock goes faster and faster. Suddenly, just as the tension reaches 200 N, the vine snaps. If the rock is moving toward the cliff at this instant, how far out on the plain (from the base of the cliff) will it land?

A wrecking ball used to knock down buildings has a mass of m = 1460 kg and is suspended from a cable of length L = 24 m. It reaches a maximum speed of v = 14 m/s while traveling in a circular arc toward the building. What is the minimum tension in N that the cable must be able to support without breaking? Assume the cable is massless.If the cable can only support a tension of 10,000 N what is the highest mass the ball can have in kg?
X Incorrect. In the figure, a small block of mass m = 0.014 kg can slide along the frictionless loop-the-loop, with loop radius R = 12 cm. The block is released from rest at point P, at height h = 5R above the bottom of the loop. What are the magnitudes of (a) the horizontal component and (b) the vertical component of the net force acting on the block at point Q? (c) At what height h should the block be released from rest so that it is on the verge of losing contact with the track at the top of the loop? (On the verge of losing contact means that the normal force on the block from the track has just then become zero). TEP (a) Number i 0.06 (b) Number Number i h Units Units Units QT R Y J 000
In her hand, a softball pitcher swings a ball of mass 0.255 kg around a vertical circular path of radius 60.6 cm before releasing it from her hand. The pitcher maintains a component of force on the ball of constant magnitude 30.6 N in the direction of motion around the complete path. The speed of the ball at the top of the circle is 14.9 m/s. If she releases the ball at the bottom of the circle, what is it speed upon release?
A certain string just breaks when it is under 23 N of tension. A boy uses this string to rotate a 660 g stone in a horizontal circle of radius 2.0 m. The boy continuously increases the speed of the stone. At approximately what speed will the string break? (Hint: you may assume that the string is about to break and it hasn't broken yet).
