Note: I already got part a, but posted it because it includes information useful for part b.
A baseball diamond is a square 90 ft on a side. A player runs from first base to second at a rate of 16 ft/s.
a)At what rate is the player's distance from third base changing when the player is 30 ft from first base?
b) At what rates are angles theta1 and theta2 (see the figure) changing at that time?
The correct answers for part b are 8/65 rad/sec (theta1) and -8/65 rad/sec (theta2)
Thanks in advance,
