Question

I am struggling to understand how to approach this problem. Can someone walk me through this problem?

A spider has been hanging outside the kitchen windown of my 6th floor
apartment for the entire semester. A bit of a high risk taker, she spins a thread of length
L, and releases herself from an angle 0, as shown below. The spider has mass m. Your
answer may be expressed in terms of any of the variables given in the problem along
with any relevant physical constants.
(a) When the spider reaches the bottom of the swing, what is the spider's speed?
Is something conserved?
(b) What's the tension in the thread at the bottom of the swing?
(c) When the spider reaches its maximum height on the other side, what's the tension
in the thread?
Draw a free body diagram for the spider and align your
y-axis with the thread - what's the spider's acceleration in the y- direction?
