... Newton’s second law of motion. Newton’s second law states that an object acted upon by an external net force accelerates in the direction of the net force; the relationship between the object’s mass, acceleration, and the net force acting on it is expressed by the equation F ma. We can derive ...

Solution
... A freight train consists of two 8.00 104 kg engines and 45 cars with average masses of 5.50 10 4 kg . (a) What force must each engine exert backward on the track to accelerate the train at a rate of 5.00 10 –2 m/s 2 if the force of friction is 7.50 105 N , assuming the engines exert identica ...

The Law of Conservation of Momentum
... This method of launching many tiny objects is taken to an extreme with ion-propulsion systems for spacecraft. Ion-propulsion systems accelerate individual ions electrically to very high speeds (~30 km/s). This is about 10 faster than a typical chemical rocket. Ion-propulsion can use solar energy to ...

PHYSICS UNIT 3 Motion
... Apply Newton’s 2nd Law: Net Force = Mass x Accel’n applies to each mass in the system and to the whole system as well. Forces between masses in the system are examples of Newton’s 3rd Law. The car is slowed down by the trailer because the trailer is pulling backwards on it. The trailer is pulled ...

Problem 1: Three forces, given by F = −2 + 2 N, F 2 = 5 − 3
... As it can be seen from the figure below, an 18kg hanging box is connected by a light, inextensible string over a light, frictionless pulley to a 10kg block that is pulled by an external force having magnitude F=300N. If the coefficient of kinetic friction between the surface and the 10kg mass is 0.1 ...
