A 700-g rock is attached to a half-meter (massless) string and is spun on the other end on vertical plane. The rock makes a complete revolution every 0.21 seconds. What is the tension of the string at the top of the circular trajectory, and at the bottom of the circular trajectory? What is the difference in total energy at the top and bottom of the trajectory?
Cord 3. Bob The Figure shows a conical pendulum, in which the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. (The cord sweeps out a cone as the bob rotates.) The bob has a mass of 0.040 kg, the string has length L = 0.90 m and %3D negligible mass, and the bob follows a circular path of circumference 0.94 m. What is the period of the motion?
A car of mass m is rounding a banked curve with radius R and banking angle 0. The curve is icy, so there is no friction between the tires and the surface. At what speed must the car take the turn in order for it not to slide up or down the incline? R Top View. Gravity is into the paper. √8 g Side View. The velocity is into the paper
A conical pendulum is set up with a bob whose mass is 6.0 kg. When it is set in motion, at a speed of 0.60 m/s, the string makes a 12.0 degree angle with the vertical. a) Find the radius of the horizontal circle the conical pendulum traces out. b) Find the length of the string.c) Find the magnitude of the tension in the string.
Figure P9.75 shows a 100 g puck revolving at 100 rpm on a 20-cm-radius circle on a frictionless table. A string attached to the puck passes through a hole in the middle of the table. The end of the string below the table is then slowly pulled down until the puck is revolving in a 10-cm-radius circle. How many revolutions per minute does the puck make at this new radius?
