Asked by Anthony
a brick is thrown upward from the top of a building at an angle of 25 degrees to the horizontal and with an initial speed of 15 m/s.
what is the velocity of the brick at the max height? (the answer is 13.6 but I don't understand why or how to do it) (i thought it would be 0m/s)

velocity at max height? horizontal velocity is 15*cosine(25)
the velocity in the vertical direction is of course, zero at the top.
