Analyze 1. What happened to the time it took for the marble to reach the table (t) as the angle of incline increased? 2. What is
the relationship between the acceleration of the marble (a) and the time it takes the marble to reach the table (t)? Draw Conclusions 1. According to your graph, what would be the acceleration of the marble at 90°? 2. Given what you know about the acceleration of Earth's gravity (g = 9.8 m/s2), is this number accurate? If not, explain why you think it is not accurate. Explore Further 1. What factors might affect the accuracy of this experiment? Describe one way you could improve the experiment's design. List any equipment you might use, and explain how you would use it. 2. If the acceleration of gravity is 9.8 m/s2, then that means an object falling at 90° will be traveling 9.8 m/s after 1 second, 19.6 m/s after 2 seconds, and so on. Use the data values in your table to sketch a rough graph of velocity versus time for the 10° angle and another for the 40° angle. What value do the slopes of these graphs represent? Which graph has the greater slope? Why?

Answer:
42.86m
Explanation:
The first thing we should keep in mind is that the watermelon moves with uniform acceleracion equal to gravity (9.81m / s ^ 2)
A body that moves with constant acceleration means that it moves in "a uniformly accelerated motion", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
When performing a mathematical demonstration, it is found that the equations that define this movement are as follows.
where
Vf=29m/s= final speed
Vo= initial speed=0m/S
g=gravity=9.81m/s^2
Y= distance traveled(m)
solving
the distance traveled by watermelon is 42.86m
