A body is moving at 70km/h and has a mass of 130kg, calculate its maximum kinetic energy.

Firstly, the speed is not given in SI units, this is modified by changing the units from km/h to m/s by the following relationship; 70km/h = (70000/3600)m/s. Once this is complete the equation for kinetic en...

A curve has equation y = e^x + 10sin(4x), find the value of the second derivative of this equation at the point x = pi/4.

Firstly, differentiate y with respect to x once to obtain the equation dy/dx = e^x + 40cos(4x). Then differentiate this resultant expression, with respect to x, to acquire a solution for (d^2)y/d(x^2) = e^x ...
