... it doesn’t matter what the horizontal speed is, gravity will affect it in the same way…that is, it will take the same time to fall at the point where the object starts to fall (y direction) the vertical velocity is 0 m/s to solve the problems, look at the x and y directions separately ...

... resultant: net force or sum of all forces. superposition of forces: the effect of any number of forces applied at a point on an object is the same as the effect of a single force equal to the vector sum of the original forces. Any force can be replaced by its components, acting at the same point. ...

... (i) When the fuel in a rocket burns, a stream of gas is produced and then escapes at high velocity through the exhaust nozzle. The exhaust gases are pushed backwards by the rocket. (ii) Therefore a reaction acts on the rocket in the opposite (upward) direction and it is this force that overcomes its ...
