Answer 2

As the pendulum approaches or recedes from which position(s) is the acceleration vector almost parallel to the velocity vector .

	position 2 only
	positions 1 and 2
	positions 2 and 3
	positions 1 and 3

Answer 3

Answer #1

1. a is the instantaneuos rate of change of velocity.

because the acceleration is due to gravity and the tension as well.

2. position 1 and 3. the acceleration at these positions is almost tangential to the path the bob follows.

Consider a simple pendulum consisting of a massive bob suspended from a fixed point by a string. Let T denote the time (period of the pendulum) that it takes the bob to complete one cycle of oscillation. How does the period of the simple pendulum depend on the quantities that define the pendulum and the quantities that determine the motion? [You need to perform a dimensional analysis to solve this one. Start by assuming T = k Inmpgq, where k...
