Two traffic cops are sitting stationary at positions ri = At t = 0, a car is at the origin with instantaneous velocity v. At that time, officers 1 and 2 measure line-of-sight speeds vi and v2 on their radar guns. Determine the car's velocity v at t = 0. î+j and r2 = -j, respectively.arrow_forwardQ.5) Determine Ixx, lyy and Ixy for the section shown below. y y²= 3x 2 y = x²/3 Xarrow_forwardProduce three isoclines with appropriate direction markers, and sketch one solution curve passing through x = 2 for the equation dy 2x. dxarrow_forward
- 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_forwardGiven: Solve the given equation below using: A.

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_forward
- 6. A Ferris wheel is 200 ft in diameter with its lowest point 3 ft off the ground. Once all the passengers have been loaded, the wheel makes one full rotation counterclockwise in 3 min. Suppose that a couple is seated at the lowest point on the wheel and are the last passengers to be loaded. a. Write a model representing the couple's horizontal position x (in feet) relative to the center of the Ferris wheel, t minutes after the ride starts. b. Write a model representing the couple's height y (in feet) above ground level, t minutes after the ride starts. c. Give the coordinates of the couple's position 2 min into the ride and tell if they are going up or down. Round to the nearest tenth of a foot.arrow_forwardQuèstion 12 The line that passes through the points (2,0), (0,1) is x+2y = c, where c = 1.
