Question 1040714: in the fastest measured tennis serve the ball left the racquet at 73.14 m/s. A served tennis ball is typically in contact with the raquet for 30.0 ms and starts from the rest. Assume constant acceleration. (a.) What was the ball's acceleration during the serve? (b.) How far did the ball travel during the serve?

(a.) What was the ball's acceleration during the serve?
:
use equation V=V_o+a*t, V_o= zero
a = v/t
73.14/.030= 2438
:
(b.) How far did the ball travel during the serve?
(73.14/2)(.030) = 1.10
