A hockey puck is hit on a frozen lake and starts moving with a speed of 10.6 m/s. Five seconds later, its speed is 6.10 m/s.
(a) What is its average acceleration?
m/s2
(b) What is the average value of the coefficient of kinetic friction between puck and ice?
(c) How far does the puck travel during this 5.00 s interval?
m

Henry,
a. a = (Vf  Vo) / t,
a = (6.1  10.6) / 5 = 0.9m/s^2.
c. d = (Vf^2  Vo^2) / 2a,
d = ((6.1)^2  (10.6)^2) / 1.8 = 41.8m.
