a basketball player is standing on the floor 12 m from the basket. the hight of the basket is 3.05m, and he shoots the ball at a 47 degree angle above horizontal from a height of 1.8m.
a) what is the acceleration of the basketball at the highest point in its trajectory?
b) at what speed must the player shoot the basketball so that it goes through the hoop without touching the backboard?
There is also blue light which has a transmitted angle in the water that is 0.56 degrees smaller than that of the red light in the water. What is the incident angle of blue light
