Can someone tell me if this is correct: How many forces act on an upwardly tossed coin when it gets to the top of its path?
A. one the force due to gravity
B. two gravity & the force in the coin itself
C. three gravity the coins internal force & a turnaround force
D. none of the above
I think it is A....if not can you give me a site where I can find it. Thanks
