In the slap shot video, and the professor said that the puck experienced "an average force of 100 pounds" which we now know is 445 Newtons of average force. The duration of this collision is .02 seconds. Calculate the Impulse in this puck/stick collision. The mass of the puck is .175 kg.

 I = 89 N s

Explanation:

Momentum is a concept that tells us how much the amount of movement of a system changes, it is described by the expression

      I = ∫ F dt = F_average   t

where F is the force and t is the time

let's calculate

      I = 445  0.2

      I = 89 N s

statement #3 on andre"s list is false.
