13. A model airplane of mass 0.90 kg flies with a constant speed of 20 m/s in a circle guided a rope 8 m long (a) [10 pts) Find the rope's tension needed to keep it in a circle. (b)[10 pts) Find the rope's tension if the rope length is doubled.
Problem 2: A mass of 0.5 kg, is attached to a mass- less string and being rotated in a vertical circle of radius of 1 m. Its motion is such that the tension in the string at location B is equal to its weight (mg). Determine a) its tangential velocity VB at B, b) the tension in string TA at A, and c) the centripetal acceleration an at C rel m 30
Consider a ball of mass 0.110 kg being spun in a horizontal circle of radius r-0.50 m, as shown to the right. When the ball reaches an angular velocity (o) of 2.00 rad/s, it is given a constant angular acceleration of a- 2.00 rads. You can assume that the radius of the circular path followed by the ball remains constant during this acceleration. After precisely 3.00 seconds of this angular acceleration, the ball breaks off the string (a) In what...
A child twirls a 0.18 kg mass attached to the end of a 47 cm long piece of string. He twirls the mass around at 2.4 revolutions per second in a vertical plane. Calculate the tension (in N) in the string when the mass is at the bottom of the circle.
A rock of mass m = 0.97 kg is attached to a massless string of length L = 0.71 m. The rock is swung in a vertical circle faster and faster up to a speed of v = 2.4 m/s, at which time the string breaks. What is the magnitude of the tension, in newtons, at which the string breaks?
006 10.0 points A model airplane of mass 0.634 kg flies in a horizontal circle at the end of a control wire of length 45.4 m with a speed of 48.2 m/s. The forces exerted on the airplane are the pull of the control wire, its own weight, and aerodynamic lift, which acts at 29.7° inward from the vertical as shown in the figure litft Compute the tension in the wire if it makes a constant angle of 29.7 with...

A lead fishing weight of mass 0.20 kg is tied to a fishing line that is 0.50 m long. The weight is then whirled in a vertical circle. The finishing line will break if its tension exceeds 100.0 N. (a) If the weight is whirled at higher and higher speeds, at what point in the vertical circle will the string break (top, bottom, or random position)? (b) At what speed will the string break?
Circle answers please
An object with a mass of m = 5.5 kg is attached to the free end of a light string wrapped around a reel of radius R = 0.275 m and mass of M = 3.00 kg. The reel is a solid disk, free to rotate in a vertical plane about the horizontal axis passing through its center as shown in the figure below. The suspended object is released from rest 6.40 m above the floor. M...
In the system shown below, there is a block of mass M = 3.6 kg resting on a horizontal ledge. The coefficient of kinetic friction between the ledge and the block is 0.25. The block is attached to a string that passes over a pulley, and the other end of the string is attached to a hanging block of mass m = 2.2 kg. The pulley is a uniform disk of radius 7.9 cm and mass 0.66 kg. Find the...
