Ask Your Teacher A 54.5-g Super Ball traveling at 29.0 m/s bounces off a brick wall and rebounds at 19.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 4.65 ms, what is the magnitude of the average acceleration of the ball during this time interval

The magnitude of the average acceleration of the ball during this time interval is 381.50

Explanation:

1 ms =

Assuming a coordinate system:

v0 = -29 m/s

v1 = 19.5 m/s (rebounds is positive)

a = Δv/Δt = = = = 381.50

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
