2. The position of a drone as a function of time is given by *(t) = ( 8 i + 1.5 k) + (-3 î + 2 j) t – 0.5 t2 j The units are missing in the constant coefficients above, i.e., "0.5" should be "0.5 m/s2". Include the correct units on all the constant coefficients in your answers below. a. What is the x-position of the drone as a function of time? b. What is the y-position of the drone as a function of time? c. How far away is the drone from its starting position at t = 3s? d. What is the acceleration vector? е. What is the velocity vector as a function of time? (One way to do this is to take the time derivative of the position vector.) f.

6. A train is moving with a constant speed. The train moves 60 meters for every 1.5 seconds that elapses. a. Assume that we get 40 by dividing 60 by 1.5. What is the name that is commonly given to a quantity represented by this number 40? b. To denote the quantity completely, what additional information must be given besides the number 40? c. How would you interpret the number 40 in this instance? Your answer should mention distance and time. d. Use your interpretation (not algebra) to find the distance the train moves in 2.5 seconds.

As a freshly graduated student from WCCI, you are aiming to become a safety engineer for Bolliger and Mabillard (B&M) so that you can help create rollercoasters for Canada's Wonderland. For many roller coasters, it is important that the rides do not come to a complete stop abruptly at the end of a ride (or else bones will break!). The final section of the rollercoaster has the cart (1.5 tons) starting at the final peak with a height of 140 metres (assume the cart starts at rest). The final section (3-4) of the ride is designed to come to a stop using a material with a coefficient of friction of 0.668. The final section is completely flat and is 393.7 feet long. The minimum time required for a ride to come to a stop safely is 6 seconds. a) What is the minimum height required for the ride to come to a stop safely? b) What is the power generated by the braking system of the ride?
