The total momentum of two marbles before a collision is 0.03 kg
m/s. No outside forces act on the marbles. What is the total
momentum of the marbles after the collision?
Select one:
.06 kg m/s
0 kg m/s
.03 kg m/s
.015 kg m/s

Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a 100 kg ball traveling at 5 m/s. a 1,000 kg ball traveling at 5 m/s would have kinetic energy. a 10 kg ball traveling at 5 m/s would have kinetic energy. a 100 kg person falling at 5 m/s would have kinetic energy. the choices for all: the same 10 times more 10 times less 100 times more 100 times less
