Physics question

3. The position of a drone as a function of time is given by m m *(t) = ( 8 i – 5 j+ 1.5 k) m + (-2 î + 4 j) t - t2j 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? What is the acceleration vector? e. What is the velocity vector as a function of time? f. At what time is the speed equal to 4 m/s?

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.
