Indiana Jones is swinging from a rope. The distance between the pivot point and his center of mass is 31.0 m. He begins swinging from rest at an angle [tex]\theta[/tex] = 17.0 degrees. Assuming the Indiana and the rope can be treated as a simple pendulum, what is the value of [tex]\theta[/tex] after 1.33s (in degrees)? i have no idea where to begin on this problem. I know that the formula for a period of a pendulum is [tex] T= 2\pi \sqrt L/g [/tex] , but i dont' know where the angle comes into play. Any help?
