1- Determine the volume of the box and the block. 2- Determine the ratio of the block to the box:
volume of block = (L)(W)(H)
volume of box. (L)(W)(H)
2.1- Multiply this number by 100 to turn it into a percent.
2.2- Complete this statement: The volume of the block is percent of the volume of the box.

3- Determine the ratio of the number of hits to the number of shots:
number of hits/100 shots
3.1- Multiply this number by 100 to turn it into a percent.
3.2- Complete this statement: The block was hit percent of the time.

4- Compare the results of step 2 to the results of step 3. Are the percentages similar?

5- Write a conclusion discussing the following items:
5.1- Based on your findings, do you think Rutherford's hypothesis was reasonable?
5.2- Restate Rutherford's hypothesis and describe how you tested it.
5.3- State whether your results support the hypothesis. If they do not, can you suggest some error in experimental procedure (other than general human error) that might explain it?
5.4- Finally, explain how this experiment confirms the nuclear model of the atom and the idea that most of the atom is empty space.

Amass m = 74 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius r = 18.4 m and finally a flat straight section at the same height as the center of the loop (18.4 m off the ground). since the mass would not make it around the loop if released from the height of the top of the loop (do you know why? ) it must be released above the top of the loop-the-loop height. (assume the mass never leaves the smooth track at any point on its path.) 1. what is the minimum speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track? 2. what height above the ground must the mass begin to make it around the loop-the-loop? 3. if the mass has just enough speed to make it around the loop without leaving the track, what will its speed be at the bottom of the loop? 4. if the mass has just enough speed to make it around the loop without leaving the track, what is its speed at the final flat level (18.4 m off the ground)? 5. now a spring with spring constant k = 15600 n/m is used on the final flat surface to stop the mass. how far does the spring compress?
