Indiana Jones is swinging from a rope. The distance between the pivot point and his center of mass is 31.00m. He begins swinging from rest at an angle theta=20.00 degrees. Assuming that Indiana and the rope can be treated as a simple pendulum, what is the value of theta after ...
A uniform horizontal bar of length L = 5 m and weight 243 N is pinned to a vertical wall and supported by a thin wire that makes an angle of theta = 39o with the horizontal. A mass M, with a weight of 300 N, can be moved anywhere along the bar. The wire can withstand a maximum...
