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.
