A soccer ball is kicked with an initial horizontal velocity of 12.0 m/s and an initial vertical velocity of 19.0 m/s
1) What is the maximum height the ball goes above the ground?
2) How far from where it was kicked will the ball land?
3) What is speed of the ball 1.1s after it was kicked?
4) How high above the ground is the ball 1.1s after it is kicked?
There are two major types of aberration (defective image formation) in lenses: spherical and chromatic. Spherical aberration comes from fact that a spherical lens has the property of focusing parallel rays to a single point only approximately.
A light wave travels from point A to point B in vacuum. hat is the difference between the number of waves between A and B with and without the glass plate in place
