3) A mass of 0.5 kg is attached to the lower end of a thin cord of which length is 2.1m. The upper end of the cord is fixed. The mass moves in a horizontal circle with constant speed. During the revolution of the mass, the cord makes a fixed angle of 20° with the vertical direction. As a result, the suspending cord traces out a cone. Determine the tension force F in the cord and the period T of...
A tether ball is attached to a swivel in the ceiling by a light cord of length L. When the ball is hit by a paddle, it swings in a horizontal circle with constant speed v, and the cord makes a constant angle beta with the vertical direction. The ball goes through one revolution in time T. Assume that T, the mass m, and the length L of rope are known, derive algebraic expression for the tension FT in the...
2. A block of mass "m" is attached to a cord of length "L", which is fixed at one end. The mass moves in a horizontal circle on a frictionless table. A second block of mass "3m" is attached to the first by a cord of the same length "L" and also moves in a circle, as shown. The period of the motion is "t". a. Write out the forces in the radial direction on each block. Given [m, L,...
One end of a cord is fixed and a 0.5 kg object is attached to the other end, where it swings in a vertical circular motion of radius 2 m. When the angle is 20 degree, the speed of the object is 8 m/s. At this instant find the tension in the string, and the radial acceleration.
A puck of mass 0.6 kg is attached to the end of a cord 1.2 m long. The puck moves in a horizontal circle as shown in the figure. If the cord can withstand a maximum tension of 250 N, what is the maximum speed at which the puck can move before the cord breaks mis 10 mis 5 m/s 20 mis 12 KN 25
A puck of mass 0.678 kg is attached to the end of a cord 0.969m long. The puck moves in a horizontal circle without friction. If the cord can withstand a maximum tension of 132N, what is the highest frequency at which the puck can go around the circle without the cord breaking?
A puck of mass 0.793kg is attached to the end of a cord 0.876m long. The puck moves in a horizontal circle without friction. If the cord can withstand a maximum tension of 131N, what is the highest frequency at which the puck can go around the circle without the cord breaking?
3. As shown on the right, a small 150. gram mass is attached to the end of a low mass string so that the center of the mass is 120. cm below the attachment point. The mass is pushed to that it moves in a horizontal circle forming a "conical pendulum" witha half-cone angle of 32.0°. (10 points) 320 a. What is the tension in the string? (5 points) m # 1 50. gramis answer: T- (5 points) b. How...
Conical Pendulum A mass attached at the end of a massless string swings around in a horizontal circle (the string sweeps out a cone). Let θ be the angle the string makes with the vertical, l be the length of the string, h is the vertical height of the string, and r is the radius of the circle. So, l is the hypotenuse of a right triangle with h and r as legs, and θ as the upper angle. The...
A ball of mass 4.4 kg is attached to a pole by two ropes: a horizontal rope under tension T1, and a rope under tension T2 which makes an angle 0 = 44.6 degrees with the vertical as shown in the diagram. The ball moves in a horizontal circle of radius L = 1.9 at constant speed of V| = 19.2 m What is the tension T? Answer in Newtons (N).
