over a rough surface by a constant force of 99.9 N acting at an angle of 29 degrees above the horizontal. You move the trunk over a distance of 79.3 m in a straight line.
The coefficient of kinetic friction is 0.111, and acceleration of gravity is 9.8 m/s^2.

How much is the work done on the block by the net force?? Answer in units of J.

A tiger leaps horizontally from a 12m high rock with a speed of 4.5m/s. How far from the base of the rock will she land?

and

A diver running 1.6 m/s dives out horizontally from the edge of a vertical cliff and reaches the water below at 3.0s later. How high ws the cliff and how far from its base did the diver hit the water?

Please show your work and explain to me how I can solve these two problems.

On my last Physics test, there was a problem concerning a cannon firing a shell at 1200 m/s at 50 degrees from the horizontal. I was to find the horizontal distance the shell traveled. What I did is I broke the 1200 m/s into its vertical and horizontal components. Then I used those numbers to figure out how long the shell would be in the air, and used that to figure out how far away the shell would be when it landed. I got the question right.

But, I'm pretty sure there's a serious difference in the answer when you stop assuming that the earth is flat. What I'd like you nifty physics experts to do is take into account the curvature of the earth and the lessened strength of gravity when far away for the earth's surface (you can continue to ignore air resistance). Did the shell clear the earth's pull entirely? Is it in orbit? Did it finally hit the other side of the earth?

What's the real answer to my test question?

What is the derivative of the function F(x)=x^x with respect to x?

I would at first think it would be x*x^(x-1)=x^x, but I don't think it is.
