We know the mass, so let's find the force of friction : F fr = µ k F N F fr = (.93)(1835 kg)(9.80 N/kg) = 16724.19 N . As the batmobile moves in the positive direction, there is friction in the negative direction, and the force of the retro thrusters on the Batmobile - we will call this force F. Now we set up a Newton's Second law: <Fnet> = ma

The Law of Conservation of Mass states that substances involved in chemical reactions do not lose or gain any detectable mass. The state of the substance, however, can change. For instance, the Law of Conservation of Mass should prove that an ice cube will have the same mass as the water that forms as the cube melts.

Conservation of Linear Momentum. Theory: The momentum p of an object is the product of its mass and its velocity: p = mv Momentum is a vector quantity, since it comes from velocity (a vector) multiplied by mass (a scalar). The law of conservation of momentum states that the total momentum of all bodies within an isolated system, p total = p1 + p
