Question

A student is instructed to perform an experiment to investigate how changing the initial velocity of a magnetic marble (A) affects the final velocity after it collides inelastically with a stationary magnetic marble (B) of equal mass on a frictionless table.

a. Suggest a way the student could change the velocity of Marble A.

b. Suggest a way the student could measure the velocity of the marbles before and after the collision?

c. During the experiment, initial and final velocity data can be collected and used to calculate momentum and kinetic energy.

i. Predict the expected relationship between initial and final velocity of ball A by drawing a line (or describing if you are unable to draw) on the axes below. Indicate the anticipated slope of the line. Justify your prediction.

ii. Predict the expected relationship between initial and final momentum of the system including both balls by drawing a line (or describing if you are unable to draw) on the axes below. Indicate the anticipated slope of the line. Justify your prediction.

iii. Predict the expected relationship between initial and final kinetic energy of the system including both balls by drawing a line (or describing if you are unable to draw) on the axes below. Indicate the anticipated slope of the line. Justify your prediction.
