Stephen is playing pool. He hits the cue ball with a force of 240 N and this takes .05 seconds. If the mass of the cue ball is .08 kg, how fast is the cue ball moving after it is hit?

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
