Kepler's third law states that the square of the period of the orbit is directly proportional to the cube of the radius of the orbit (T^2=kr^3) where r is some constant to be determined. This can be deter...

Fermat's Principle states that light will always take the path of least travel TIME (NOT DISTANCE), at a first glance it appears that the path of least time would be a straight line from A to B, but this ...

From the question asked, we need to identify the key bits of information.

Firstly, we are asked to find the de Broglie wavelength, so we write down the de Broglie relation:

lambda = h/p

First, find the formula for the time taken, t, for the projectile to travel the distance. Using the fact that the projectile reaches a velocity of zero at a time of 0.5t when at its maximum height and acc...

The key to solving this problem is realising that gravitational potential energy and elastic potential energy need to be equated. The gravitational potential energy of an object of mass m at height h abov...
