Here is the question but before I begin, I've noticed that their weight are expressed in N.
Do I have to do a conversion? or is that correct? I was just confused..
Peter and John are playing a game of tug-of-war on a frictionless, icy surface. Peter
weighs 539N and John weighs 392N. During the course of the game, John accelerates
toward Peter at a rate of 3.0m/s[tex]^{2}[/tex].
a) What is the magnitude of the force that Peter exerts on John?
F[tex]_{N}[/tex] = F[tex]_{P}[/tex] - F[tex]_{J}[/tex]
F[tex]_{N}[/tex] = 539 - 392
F[tex]_{N}[/tex] = 147N
b) What is the magnitude of the force that John exerts on Peter?
F[tex]_{N}[/tex] = -147
c) What is the magnitude of Peter's acceleration toward John?
d) Sarah decides to join the game as well. Now Peter pulls on Sarah with a force of
45.0N[E] and John pulls on her with a force of 25.0N[N] What is Sarah's resultant
acceleration, if she weighs 294N?
