Question

Map Sapling Learning During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.145-kg baseball cra shing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 16.1 m7s, shaiters thie glass as it passes through, and leaves the window at 11.7 m/s with no change of direction. What is the direction of the impulse that the glass imparts to the baseball? The direction of the ball's motion osite the direction the ball's motion O Neither of these Calculate the magnitude of this impulse (a positive number) Number 0 N s The ball is in contact with the glass for 0.0104 s as it passes through. Find the magnitude of the average force of the glass on the ball (a positive number). Number Previous Gve Check Answer 0 Next Exit > 9 Hint

Explanation / Answer

Calculate the impulse

I= change in momentum

I=m(vf-vi)

I=0.145(11.7-16.1)

I=-0.638 N.s

Hence the magnitude of impulse is 0.638 N.s

Impulse=Fdt

F=I/dt

F=0.638/0.0104

F=61.34 N
