- 10. [Motion in R³] A drone has an initial position of (3,1,2) and an initial velocity of (-2,5,1). The drone's acceleration can be given by the function a(t) = (4 - 6t, 9 sin(3t), 10e-2t). (a) Derive a formula for the position of the drone as a function of t. (b) If the drone flies for 4 seconds, where does the drone end up?arrow_forward2. The Batmobile travels in a straight line such that t seconds after passing through Arkham, its velocity v(t) in meters per second is given by v(t) = 5t3 + (20 – 30k)t² – 100kt + 200k + 50 where k is constant. (a) Find an expression for the acceleration of the Batmobile in terms of k and t. (b) Suppose that the acceleration of the Batmobile five seconds after passing through Arkham is 175 m/s?. Determine the value of k five seconds after passing through Arkham. (c) Using the value of k from item (b), find the range of values of t for which the Batmobile is accelerating positively. (d) Using the value of k from item (b), determine the values of t when the Batmobile is accelerating at its fastest and slowest within six seconds of passing through Arkham.arrow_forward1. A particle moves along a vertical coordinate axis so that its position at any time t20 is given by the function s() =r' - 6r² + 9t + 5, where s is measured in centimeters and t is measured in seconds. (e) Describe the motion of the particle for t20. Answer the following questions with justification: • When is the particle moving up? • When is the particle moving down?. • When is the particle at rest? • When is the particle speeding up? • When is the particle slowing down? because because because because because • Find the particle's acceleration each time the velocity is zero. • Find the total distance traveled by the particle from 0 to 3 seconds.arrow_forward
