Hi,

I am preparing for a test and have the following question.

there is the image attached too.

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 θ = 19.0o as shown in the figure. Assuming that Indiana and the rope can be treated as a simple pendulum, what is the value of θ after 1.27 s (in degrees)?

so i this is a harmonic motion question. as far as i understand i can use the

formula of location (x=...) but use angles to represent the location and thus get the answer. but somehow i get the wrong answer all the time.

could some one show me how it is done so i can see where i am wrong?

thanks
