A hockey puck was moving at +22.8m/s. When it hit the goalie's glove, it showed down and came to a stop in +0.10m.
a) How far was the player from the goalie if it took 0.30s to travel from the player's stick to the goalie's glove?
b) How long did it take for the puck to stop after it hit the goalie's glove?
c) What was the acceleration of the puck as it stopped?
c. V^2 = Vo^2 + 2a*d.
0 = 22.8^2 + 2a*0.1,
a = -
b. V = Vo + a*t.
V = 0, Vo = 22 m/s, a = Value calculated in "c", t = ?.
a.
