If light bounces off of a mirror, shouldn’t there be an equal and opposite reaction to the force, giving the mirror some energy, and the light will lose some velocity…. but then light is always moving at the speed of light so how is it compensated? Will the photon just pull energy out of nowhere and continue at the speed of light?

Whiterose7 asked:


A ball is launched with initial speed v from ground level up a frictionless slope. The slope makes an angle theta with the horizontal. Using conservation of energy, find the maximum vertical height, h max, to which the ball will climb. Express your answer in v, g or theta.

Can someone please show me how to do this problem? Thank you!!
