A ball is thrown up with an initial velocity of 8 m/s and initial height of 1.5m above the ground. Calculate the maximum height the ball reaches and the time it takes to get there.

Travelling upwards u = 8m/s v = 0 m/s a = -9.8m/s S = ? t = ? v = u + at v 2 = u 2 + 2a(S - 1.5) 0 = 8 -9.8t 0 = 64 + 2*(-9.8)*(S - 1.5) 9.8t = 8 19.6*(S - 1.5) = 64 t = 0.816s (3.sf) S - 1.5 = 3.265m S = 4....

Differentiate the function f(x) = x^2 * e^2x with respect to x

l e t u = x^2 let v = e^2x du/dx = 2x dv/dx = 2e^2x d/dx = v du/dx + u dv/dx = 2x e^2x + 2x^2 e^2x Therefore d/dx = 2x*e^2x * (1 + x)
