In which collisions did the shooter marble change direction? How did the mass of the target marble (stationary) compare with the shooter marble in these collisions?

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch
