During the annual shuffleboard competition, renee gives her puck an initial speed of 9.32 m/s. once leaving her stick, the puck slows down at a rate of -4.06 m/s/s.
a. determine the time it takes the puck to slow to a stop.
b. use your initial speed and the calculated time to determine the average speed and the distance which the puck travels before stopping.

A.) V = u + at
0 = 9.32 - 4.06t
4.06t = 9.32
t = 9.32 / 4.06 = 2.3 secs

b.) Average speed = |0 - 9.32| / 2 = 9.32/2 = 4.66 m/s
v^2 = u^2 + 2as
0 = (9.32)^2 + 2(-4.06)s
8.12s = 86.8624
s = 86.8624 / 8.12 = 10.7 m
distance = 10.7 s
