A sled with a mass of 30.0 kg rests on a horizontal sheet of essentially frictionless ice. It is attached by a 5.00-m rope to a post set in the ice. Once given a push, the sled revolves uniformly in a circle around the post as shown in the figure. If the sled makes five complete revolutions every 60 s, find the force Fexerted on it by the rope. -R- O 15.5 N O 30.5 N O 31.5 N O 41.1 N O there is no answer
A string can support a stationary hanging load of mass 25 kg before breaking. a) Calculate the maximum tension that the string can support. b) Suppose one end of the string is attached to an object of mass m = 3 kg, while the other end is fixed to the center of a frictionless table as shown in the figure. When given an initial speed, the object moves along a horizontal circle of radius R = 0.8 m. Calculate the maximum speed the object can have before the string breaks.
A mass M of 3.60E-1 kg slides inside a hoop of radius R=1.60 m with negligible friction. When M is at the top, it has a speed of 5.21 m/s. Calculate the size of the force with which the M pushes on the hoop when M is at an angle of 41.0°.
