A hockey player uses a leaf blower to apply a constant force on a hockey puck. The puck accelerates in a straight line across the ice. Then another player applies an equally strong, constant force on the puck in the opposite direction. How will the puck move in response?

    It will stop immediately. It will not slow down, but continue moving at constant velocity. It will slow down and eventually stop. It will slow down, then continue moving at constant velocity.

    if there is an equal force on both sides then the puck shall not move

    because it couldn't continue to move with equal forces on both sides

    A 250-N box is at rest on a frictionless horizotal floor. Then a person shoves the box with a non-zero force of magnitude P. Which statement best describes the relationship betweeen P and the motion of the box after it was shoved? do you know this one? @g-lax4

    The box will move with constant velocity at a speed that is directly proportional to P. The box will accelerate across the floor at a constant rate that is directly proportional to P. The box will not move when P < 250 N, but otherwise will accelerate at a constant rate that is directly proportional to P. The box will begin moving at a speed that is directly proportional to P, then will gradually slow to a halt.

    a body in moving with constant velocity continues to be move with constant velocity unless acted upon by a net external force

    it will accelerate for as long as the the person was shoving....after that it will move at a constant velocity

    The box will accelerate across the floor at a constant rate that is directly proportional to P. oh so its not this one right

    yeah...once the "shoving" is done...there is no force being applied on the box. so it has to move at a constant velocity.
