- 1. A space-ship is heading towards a planet, following the trajectory, r(t) = (Ae-¹² cos(3t), √2Ae-t² sin(3t), - Ae-t² cos(3t)), where A 50, 000km and the time is given in hours. (a) The planet is centred at the origin and has a radius, rp = 2,000km. At what time does the ship reach the planet? Give your answer (in hours) both as an exact expression and as a decimal correct to 4 significant figures. (b) To 4 significant figures and including units, what are the velocity and speed of the space-ship when it reaches the planet?arrow_forwardIn a 24-hour period, the water depth in a harbour changes from a minimum of 3/2 m at 2 am to a maximum of 7 at 8:00 am.

- Problem 2: a. Using the chain rule dy dy dr dr dt dt compute 4 using the parametric equations x = cost, y = sin t, te (-0, 00) Write as a function (i) of t. (ii) of æ and y. (Express the derivative as a rational function, not a piecewise-defined function.) b. Use the chain rule to express in terms of d (dy dt dr dr and dt c. Use the result in part (a) and the chain rule again to compute 4 as a function (i) of t. (ii) of r and y. (Express the second derivative as a rational function, not a piecewise-defined function.) d. Find the derivatives and 4, as in the previous parts, for the parametric equations x = cos 3t, y = sin 3t, te (-0, 0). e. More generally, let f(t) and g(t) be differentiable functions defined over t € (-0, 0). Suppose the curve C1 has parametric equations r = f(t), y = 9(t), te(-∞,00) and the curve C, has parametric equations x = f(2t), y = g(2t), te (-0, a0). Compute both of the derivatives 4 for C1 and for C2, then describe the relationship between these derivatives…arrow_forwardHiw. Solue the PDE: (D% - 4Dx Dy+ 3 Dj )u = = Cos (2x+y)arrow_forwardA.

- Question 3 Sheep's Wool Length: For sheep maintained at high environmental temperatures, respiratory rate, r(per minute), increases as wool length, /(in centimetres), decreases. Suppose sheep with a wool length of 2 cm have an (average) respiratory rate of 160, and those with a wool length of 4 cm have a respiratory rate of 125. Assume that r and / are linearly related. a) Find an equation that gives r in terms of /. b) Find the respiratory rate of sheep with a wool length of 1 cm.arrow_forwardB 2.arrow_forwardFind the general solution and sketch the phase portrait of z = ( 1 1 Z 4 -2arrow_forward
