One billiard ball is shot east at 2.2m/s. a second, identical billiard ball is shot west at 1.2m/s. the balls have a glancing collision. not a head on collision, deflecting the second ball by 90 degrees and sending it north at 1.6m/s. what are the speed and direction of the first ball after the collision?
/s

south of east

β= 57.99 south of east

Explanation:

?

Velocity in axis x the two balls come one from east and west

Velocity in axis y initial is zero so:

Angle is find using:

tan(β)=

it is the second option.

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
