1. When using a loaded cart, the photogate may measure speeds that are either unexpectedly small or large. This is likely due to: (Refer to: http://www.physics.qc.edu/files/524 for answers)

a. most of the energy of the system is in the loaded cart

b. the photogate being triggered by some part of the extra mass

c. the mass entry in the Capstone software is too large

d. most of the momentum of the system is in the unloaded cart

e. the mass entry in the Capstone software is too small

f. most of the energy of the system is in the unloaded cart

2. When triggering the "explosion" by releasing the spring, it is important to: (Refer to: http://www.physics.qc.edu/files/524 for answers)

a. press in such a way that you don't add too much external force to cart 2

b. press in such a way that you don't add too much external force to cart 1

c. only use your finger

Explanation / Answer

As the photogate is triggered by some part of the extra mass, the velocity will be small. Therefore, the correct option is (b).
