To answer the questions put in an initial y position of 30, an initial velocity of 10m/s at 45 degrees an a gravitational force of 5N at 270 degrees. Then shift to the time plot view. Set the observation time limit so as to quit looking when the ball hits the ground. If you want to change a force after you have entered it go back to the free body diagram and click on the force vector description on the screen. Then edit the force to the desired values.

The answers to all the questions may be read directly from the plot. Notice that this time you need to use the cursor to get the maximum height but may use the upper vertical limit to get the x distance at impact. By placing the cursor at the right end of the the x line you may read off the distance from the building to the impact point. An elevation of 45 degrees means that the x and y positions are equal, which happens where the x and y plot lines cross. Using the cursor you can find that time.
