Question

A football is thrown in the air so that it's horizontal velocity is 30ft/sec and its vertical is 20ft/sec. Find the velocity of the football.

At what angle of elevation was the football thrown?

Answer 1

can you draw what is going on in the problem?

Answer 2

thats all my professor gave me

Answer 3

You are advised to draw the vector,
starting with its tail at (0,0) and its other end at (30,20),

from that get the vector velocity length as v= sqrt(x^2+y^2)
and the direction @ from tan@ = y/x
