A2000kg suv accelerates from rest at a rate of 3.00m/s^2. the total amount of force resisting its motion 1500n. how much force is applied to the suvs tires by the ground to make it accelerate?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
