A van of mass 2150kg with a driving force of 10,000 is accelerating at 3 m/s^2. Find the resultant force acting in the van, and also the frictional force on the van.

We have values for the mass and the acceleration of the van, so we can work out the resultant force acting on it using Newton’s second law: F r = ma F­ r­ = 2150 x 3 = 6450N Driving force – Resultant force =...

Express (5x + 4)/(x +2)(x - 1) in partial fractions.

To put this equation into partial fractions we need to consider it in the form: (5x + 4)/(x +2)(x - 1) = A/(x + 2) + B/(x - 1) where A and B are numbers we are trying to find. To do this we need to multiply ...

Given the equation 3x^2 + 4xy - y^2 + 12 = 0. Solve for dy/dx in terms of x and y.

Here the key is to remember to differentiate with both x and y with respect to x, where the differential of y is dy/dx. Consider the first term, 3x 2 : This differentiates to 6x. This is done by multiplying ...
