11/27/2017 11:55 PM0/10 Gra Print il Calculator -Periodic Table Question 4 of 10 Map During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.147-kg baseball through the pane of a second-floor window in a nearby building. The ball strikes the glass at 15.3 ms, shatters the glass as it passes through, and leaves the window at 10.7 m/s with no change of direction. What is the direction of the impulse that the glass imparts to the baseball? O The direction of the ball's motion O of the ball's motion O Neither of these posite the direction Calculate the magnitude of this impulse (a positive number). Number N-S 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). about us careers privacy policy terms of use contact us help 27 F4 F5 F6 FT F8

Explanation / Answer

Change of impulse=change in momentum

Impulse=mass*change in velocity=0.6762 kg.m/s

Direction=opposite to direction of motion of ball

Force=impulse/time=64.4N
