A ball is thrown eastward into the air from the origin (in the direction of the positive x-axis). The initial velocity is 40 i + 64 k,?
. ft from the origin at an angle of ° from the eastern direction toward the south.
With what speed does the ball hit the ground? (Round your answer to one decimal place.)
when the z component is zero t=0 and t=2
I plugged in t=2 into my position function and tried to do inverse tan to get the first two parts, but my answers are wrong. Can you help me see where I went wrong?
