Consider a conical pendulum with a bob of mass m = 95.0 kg on a string of length L = 10.0 m that makes an angle of ? = 3.00° with the vertical. (Consider + to be towards the center of the circular path and + to be upward.)
A.) Determine the horizontal and vertical components of the force exerted by the string on the pendulum.
B.) Determine the radial acceleration of the bob.
A steel cable with total length 20 m and mass 100 kg is connected to two poles. The tension in the cable is 2,000 N, and the wind makes the cable vibrate with a frequency of 2 Hz. compute the wavelength of the resulting wave on the cable.
A 2.5kg mass is attached to a spring and placed on the horizontal, smooth surface. A horizontal force of 18.4 N is necessary to hold the mass at rest while it is pulled 0.210 m from its equilibrium position.
