Answer:
what
ITS BLANK FOR ME I WISH I COULD HELP YOU
Impulse = Ft=mΔv => Δv = Ft/m = 4.28/0.18 = 23.78 m/s
But,
Δv = v1-v2, where v1 = initial velocity = 16 m/s, v2 = final velocity
Therefore,
v1 - v2 = 23.78 => v2 = v1 - 23.78 => v2 = 16 - 23.78 = -7.78 m/s
The velocity of ball after the force is 7.78 m/s in the direction of the force.
The correct answer would be A
You could put sheet metal lining the bottom or something similar to that.. yOU could use rubber to make it have more friction
