Two forces P and Q act on an object of mass 16.0 kg with Q being the larger of the two forces. When both forces are directed to the left, the magnitude of the acceleration of the object is 0.900 m/s2. However, when the force P is directed to the left and the force Q is directed to the right, the object has an acceleration of 0.400 m/s2 to the right. Find the magnitudes of the two forces P and Q in newtons.

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.
