ATTN: DRWLS RE: PHYSICS
posted by samir on .
pete and john play a game of tug f war on a frictionless icy curface. pete weighs 539 N and john weights 392 N. during the course of the game, john accelerates toward pete at a rate of 3 m/s^2
a)what's the magnitude of the force that peter exerts on john?
b)what's the magnitude of pete's acceleration toward john?
I am not sure what formula to use, pleaase help!

The center of mass will remain in the same place in this frictionless situation
a) Use F = ma
Solve for the F
b) Also use F = ma on Pete, with the same F, and solve for a(of Pete).
The F will be the same on both, but in opposite directions.
QUESTION: DO I HAVE TO CONVERT THE WEIGHT TO MASS BY DIVIDING THE N BY 9.8M/S^2? THANKYOU.

Yes, you should convert weight to mass.
