We need to find the x and y components of this initial velocity. Using a simple triangle, we find that it is: This wants us to find the maximum height of the arrow. Plug these values into a chart for y-components: This will help find the maximum height. Now with t, we can solve for y, the maximum height. The max height "y" that we solved for only tells you how high from the starting point it is.
So you must add 10m to get the total height from the ground. To solve where the arrow lands, work in x-components. Remember that acceleration in the x-direction is 0 in this case. In this case, you must find the final velocity in the x and y direction, just before it hits the ground, and use vector addition to combine them.
