Lecture 2 Newton`s laws of motion
... Momentum is also a vector quantity that has the same direction as that of the velocity. Newton's First Law of Motion (Law of Inertia) Every object continues in its state of rest or uniform motion unless made to change by a non-zero net force The inertia of an object is its tendency to resist changes ...

... (a) When the particles are as close as they can get, the relative velocity between them is zero. So, they are both moving at the same speed, V . From the conservation of momentum, mv0 = (m + 4m) V = 5mV . So, we can see immediately that V = vα = 51 v0 . (b) When the particles are far apart, they are ...

... 27. A certain airplane has a speed of 290 km/h and is diving at an angle of θ = 300 below the horizontal when the pilot releases a radar decoy. The horizontal distance between the release point and the point where the decoy strikes the ground is d = 700 m. (a) How long is the decoy in the air? (b) ...
