A hockey player applies an average force of 80.0 N to a 0.25 kg hockey puck for a time of 0.10 seconds. Determine the impulse experienced by the hockey puck.

A baseball of mass 0.145 kg is pitched at a speed of 39.0 m/s, the ball is hit back towards the pitcher with a speed of 52.0 m/s. I) What is the magnitude of the impulse delivered by the bat to the baseball? (a) 13.2 kg m s (b) 1.89 kg m s (c) 13.0 kg m s (d) 943 kg m s II) Find the magnitude of the average force, in kN, exerted by the bat on the ball if the two are in contact for 2.00x10° s.

During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.149 kg baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 15.9 m/s, shatters the glass as it passes through, and leaves the window at 10.5 m/s with no change of direction.   What is the direction of the impulse that the glass imparts to the baseball? opposite the direction of the ball's motion neither of these in the direction of the ball's motion   Calculate the magnitude of this impulse (a positive number). impulse:   The ball is in contact with the glass for 0.0105 s as it passes through. Find the magnitude of the average force of the glass on the ball (a positive number).

A 0.277-kg volleyball approaches a player horizontally with a speed of 14.9 m/s. The player strikes the ball with her fist and causes the ball to move in the opposite direction with a speed of 21.8 m/s. (a) What impulse is delivered to the ball by the player? (Take the direction of final velocity to be the positive direction. Indicate the direction with the sign of your answer.) kg. m/s (b) If the player's fist is in contact with the ball for 0.0600 s, find the magnitude of the average force exerted on the player's fist. N
