A 0.50 kg bob swinging at the end of a string with negligible mass undergoes simple harmonic motion. Various positions along the bob's arc are labeled 1 thru 5. Point 3 is the lowest point of the swing and points 1 and 5 represent the bob's maximum displacement from the vertical.

a) Between what two points does the bob gain the most speed?b) How long does it take the pendulum to swing from point 1 to point 5?c) What is the speed of the pendulum at point 3?d) What is the tension in the string at point 3?e) What is the tension in the spring at point 5?f) Describe one modification you could make to double the period of oscillation
