If the force on an object is negative, what is known about the change in velocity? O The velocity will decrease.
O The velocity will increase.
O The velocity will not change.
O The object will change direction.

What properties of a moving object are used in determining the object's energy of motion

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.

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?
