A small rock with mass 012 is fastened to a massless string, Ask an Expert

Academics

A small rock with mass 0.12 is fastened to a massless string with length 0.80 to form a pendulum. The pendulum is swinging so as to make a maximum angle of 45 with the vertical. Air resistance is negligible. Part A What is the speed of the rock when the string passes through the vertical position? Express your answer using two significant figures. Part B What is the tension in the string when it makes an angle of with the vertical? Express your answer using two significant figures. Part C What is the tension in the string as it passes through the vertical? Express your answer using two significant figures.
