T=9g/5 ms^-2m=2 kgtime for higest point = 7/2 sec

I have a labelled screenshot of how to go about this question

To find the coordinates of the point, we have to solve the equations simultaneously. To do this, we need the same number for the coefficient of x or y in each equation. Arbitrarily, we will chose to match...

First we will differentiate y to find dy/dx= 4x³-16x. Stationary points exist at dy/dx=0 so we set 4x³-16x=0 and solve for x. x(4x²-16)=0. So x=0 or 4x²-16=0. I...

First remember that a parametric curve z = (x(t), y(t)) can be differentiated using the following formula (derived using the chain rule): dz/dt = (dy/dt)/(dx/dt). We should now find dy/dt and dx/dt (which...
