In a physics lab experiment for the determination of moment of inertia, a team weighs an object and finds a mass of 4.98 kg. They then hang the object on a pivot located 0.172 m from the object's center of mass and set it swinging at a small amplitude. As two of the team members carefully count 107 cycles of oscillation, the third member measures a duration of 251 s. What is the moment of inertia of the object with respect to its center of mass about an axis parallel to the pivot axis

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
