The bigclaw snapping shrimp shown in Figure P7.14 is aptly named—it has one big claw that snaps shut with remarkable speed. The part of the claw that moves rotates through a 90° angle in 1.3 ms. If we assume that the claw is 1.5 cm long and that it undergoes a constant angular acceleration:

a. What is the angular acceleration in rad/s² ?

b. What is the final angular speed of the claw?

c. What is the tangential acceleration of the tip of the claw?

d. How fast is the tip of the claw moving at the end of its motion?
