Your marble slide is 60 cm high and your marble is 7 grams. Given gravity is 9.81 m/s2, what is the potential energy, in Joules, of the marble at the starting point?
412.02 J
4.1202 J
0.041202 J
0.41202 J
Now, your marble has moved down to 50 cm. State its potential energy at this moment.
0.034335 J
0.34335 J
3.4335 J
34.335 J
At this 50 cm point, what is the marble's velocity to 3 significant figures?
1.96 m/s
1.40 m/s
0.00687 m/s
4.65 m/s
Now your marble is moving up again. What is the height of the marble if you want the marble to have a velocity of 0.05 m/s correct to 4 significant figures ?
0.6 m
0.5999 m
0.5998 m
0.5988 m
The marble moves down again to a height of 20 cm. What is its velocity, correct to 3 significant figures?
7.85 m/s
7.84 m/s
2.81 m/s

The marble moves up again to achieve a velocity of 2.4 m/s. What is the marble's height, correct to 3 significant figures?
30.6 cm
30.7 cm
30.8 cm
30.9
The marble is at the bottom (height is 0 cm) of your marble slide. What is its velocity correct to 3 significant figures?
3.33 m/s
