Question

a hockey puck of mass 0.05kg sliding on the ice with velocity 20m/s is stopped by a goalie in 0.10sec. what is the magnitude and direction of the force exerted by the goalie on the puck.

Answer 1

Impulse=change momentum
force*time=mass*(0-20)
force= .05*-20/.1 notice the direction is opposite the initial velocity

Answer 2

while blocking shots is great, its also means the play is in our end....hold on to the puck, cratee more offense, and we will play in our own end less therefore have less shots to block
