An image of a cue ball striking the surface of a pool table is shown. all of the
following describe the acceleration of the cue ball except -
the ball changed direction when it hit the side of the table.
the ball traveled at 30 cm/s while it was moving.
the ball was at rest until it was struck by the pool cue.
the ball eventually came to a stop due to friction.

sine

step-by-step explanation:

overpriced

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
