Two boys, one with a mass of 60 kg and the other with a mass
of 90 kg, are standing side by side in the middle of an ice rink.
One of them pushes the other with a force of 360 N for 0.10 s.
Assuming that the ice surface is frictionless:
(a) What is the acceleration of each boy?
(b) What speed will each reach after the 0.10 s?
(c) Does it matter which boy did the pushing?
