The curve, C has equation y = 2x^2 +5x +k. The minimum value of C is -3/4. Find the value of k.

Notes: At the minimum point of the curve, the gradient is = 0. You can find the gradient of a curve by taking the derivative of a point in the curve. We also know that when the curve is at a minimum, y =-3/4...

A simple pendulum is an example of a system in Simple Harmonic Motion, using conservation laws find a) the greatest speed of the bob and b) the magnitude of speed at a height of 1.0cm above the minimum point. Given it starts at rest, at a height of 20cm.

As this is an isolated system and a simple pendulum starting at rest, at maximum height, all the energy is in potential energy. The known equation for potential energy is simply mgh (mass x acceleration due ...
