Method
The A3 sheet of white paper was attached to the board, with drawing pins, and the board was placed underneath a book, to put it on a slight incline. Using a protractor, lines were drawn on as a guide for where to line up the marble. The lines were drawn at 30 O, all the way to 70 O, at 5O intervals. A runner was needed to drop the marble down to the inclined board. A piece of card was used, that was bent in half to create a runway. Wherever the marble went off the board, was marked. The result was confirmed by measuring from the point the marble was thrown to the point it fell of the board.

We produced the test a couple of times to find the best results.

Conclusion
Prediction: At 45 degrees the marble will travel the longest.
At 45 O the vertical velocity and the horizontal velocity are the same.
Example:
In the vertical direction the object decelerates at 10ms-2(approx).
It will take exactly 1 second for it to reach its maximum height. This is because of the following. 10ms-2 means every second velocity decreases by 10ms-1. It will take half a second to decrease by 5ms-1. Therefore, 5/10 = 0.5, Decrease in velocity / deceleration. 2 x 0.5 = 1second.

During this one second, the object will travel a horizontal distance.
Range = horizontal velocity x time
= 5 x 1
