A pendulum consists of a small object called a bob hanging from a light cord of fixed length, with the top end of the cord fixed, as represented in Figure OQ5.6. The bob moves without friction, swinging equally high on both sides. It moves from its turning point A through point B and reaches its maximum speed at point C. (a) Of these points, is there a point where the bob has nonzero radial acceleration and zero tangential acceleration? If so, which point? What is the direction of its total acceleration at this point? (b) Of these points, is there a point where the bob has nonzero tangential acceleration and zero radial acceleration? If so, which point? What is the direction of its total acceleration at this point? (c) Is there a point where the bob has no acceleration? If so, which point? (d) Is there a point where the bob has both nonzero tangential and radial acceleration? If so, which point? What is the direction of its total acceleration at this point? Figure OQ5.6
The mass of the ball is 0.10 kg and the string is 45 cm long. If the tension in the string when the ball is at the top of the circle is 5.75 N, what is the speed of the rock at that location?
A string under a tension of 49.5 N is used to whirl a rock in a horizontal circle of radius 2.55 m at a speed of 20.3 m/s on a frictionless surface as shown in the figure below. As the string is pulled in, the speed of the rock increases. When the string on the table is 1.00 m long and the speed of the rock is 49.5 m/s, the string breaks. What is the breaking strength, in newtons, of the string? = N
You are playing a game and you push a cart to give it in. speed. The cart starts at the bottom (zero) of a ramp and after reaching the top of the ramp, the cart travels across a horizontal track w/ friction. The mass of the cart is 44 x 10^-3 kg. The ramp is 56 cm high. The length is 70 cm. What can you infer of the intial speed in (m/s)
A roller coaster cart is moving over the top of a circular hill that has a diameter of 56 m. What is the fastest safe speed that the roller cart can go over the top of the hill? (that is, at what speed will the cart begin to lose contact with the track?). Assume a coefficient of friction of 0.7.
a tetherball on a 1.55m rope is struck so that it goes into circular motion in a horizontal plane, with the rope making a 12 degree angle to the horizontal. what is the balls speed
A frictionless block of mass 0.5 kg slides down a ramp of height 0.2 m and onto a horizontal frictionless table. A circular frictionless wall forces the block to move in a circular path. If the radius is 0.5 meters, calculate the time it takes the block to get from P to A, 1/4 the way around the circle.
A 0.1 kg ball is attached to a string and whirled around in a circle overhead. The string breaks if the force on it exceeds 60 N. What is the maximum speed the ball can have when the radius of the circle is 1 m?
A carousal has a radius R=7 m, with cables tying the seats being L=10 m long. What should be the speed of the seats so that the cables make an angle of A= 19 degrees with the vertical.
A string under tension of 50.0 N is used to whirl a rock in a horizontal circle of radius 2.5 m at a speed of 20.4 m/s on a frictionless table. The string passes through a small hole in the table at the center of this circle. As the string is pulled in, the speed of the rock increases. When the string is 1.00 m long and the speed is 51.0 m/s, the string breaks. What is the breaking strength, in Newtons, of the string?
