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.

  • physics homework -

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