A 1.0 kg pendulum bob is suspended from a string 1.0 m long. The pendulum swings until the string makes an angle of 22 degrees with the vertical. At this point
I can't remember
The Attempt at a Solution
a.) What is the tension in the string?
Answer: Ft = mgcostheta Ft = 9.09N
b.) What is the component of the force of gravity at right angles to the string?
Answer: Fg = mgsintheta = 3.67N
c.) What is the acceleration of the pendulum bob?
Answer: a = gsintheta = 3.67 m/s^2
d.) If the pendulum is held with a string fastened to the bob and held horizontally as shown, what would be the tension in the original string (not the horizontal one). (3 marks)
I don't know the answer to part D
The graph looks like this:
