okay c for findind out the force u need to know the formluae f=change in p/change in t(p means momentum)
so the change in p is 0.0465(18.6+19)/(12.5/1000)

Goodluck to everyone in their exam(s) tomorrow. Have a good night rest and lets hope to do our best! :) I am hoping for an A and will fight for it in that 1 hour tomorrow. Review what you can but don't try to cram anything tonight. Sleep is as important as knowledge.
