with an initial velocity of at 36.9° above the horizontal.

The ball will hit the building in

A. 4.0 s. B. 5.0 s.

C. less than 4.0 s. D. more than 5.0 s.

2. If the cannonball in the previous question is fired horizontally

from a 150-m-high cliff, but still 400 m from the building, then

the ball will hit the building in

A. 4.0 s. B. 5.0 s.

C. less than 4.0 s. D. more than 5.0 sI used x =(Vo * Cos 36.9)t and got 5.0 s, which is correct, but i don't know how to solve for #2
