1. A set of parametric equations are given as: = cos(2) = 33 + 2 Find when = 2 [6] 2. Use implicit differentiation to find for the following. a) 3 = 2 [6] b) .cos() + 2.ln() = 43 [6] 3. Acceleration is the derivative of velocity, = . When modelling the air resistance on a car, an engineer finds that its acceleration is given by = —0.25 If the velocity = 20 at time = 0, find an explicit equation for (). [7]
