Using the equation V2 = U2 + 2as, where V = final velocity, U = initial velocity, a = acceleration, s = displacement, we can substitute in the values given in the question t...
Qui and Que are relative pronouns. That means that they are used to form one sentence out of two different ones to avoid repetition. Although both pronouns serve the same purpose, they a...
v2/r, towards the center of the circle.Remember that acceleration is the rate of change of velocity, not merely of speed. This means that the change in direction is im...
Firstly differentiate the function:f(x) = x3 + 3x2 + 2x + 5 (function)f'(x) = 3x2 + 6x + 2 (gradient function)Stationary points are points where the graph ...
First simplify the equation of the curve y= x^4 - 3x^3 .The gradient is the differential.To differentiate, bring down the power and take one from it.x^4 becomes 4x^3-3x^3 becomes (-3x3)= -9x^2dy/dx= 4x^3 ...
