(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In Denver, children bring their old jack-o-lanterns to the top of a tower and compete for accuracy in hitting a target on the ground. Suppose that the tower height is h = 10.80 m, and that the bulls-eye's horizontal distance is d = 3.4 m from the launch point. (Neglect air resistance.)

If a jack-o-lantern is given an initial horizontal speed of 3.3 m/s, what are the direction and magnitude of its velocity at the following moments in time? (Let the +x axis point to the right.)

(a) 0.75 s after launch

_____________.° (below the +x-axis)

____________ m/s

(b) just before it lands

_______________ ° (below the +x axis)

______________ m/s

2. Relevant equations

I am not entirely sure but I believe the relevant equations are....

Vot + .5gt^2

d = 3.4m

h= 10.80m

It would be great if someone could give me the required equations and method to solving this kind of problem. Thanks.

3. The attempt at a solution

I am confused how to proceed or all that is required in the solution of this problem.

What I have done so far is substituted into the Vot + .5gt^2 to find vertical and horizontal (x and y) distances. I did this by using the equation given .75 seconds accounting for the initial velocity on the horizontal (3.3 m/s). I am unsure how to proceed though or if i am even doing this right. Very confused.
