A model rocket is launched vertically with an engine that is ignited at timet = 0, as shown above. The engine provides enough force such that the rocket has an upward acceleration of 30 m/s² for 2.0 s. After 2 seconds, the engine stops, and the rocket proceeds to reach its maximum height. Upon reaching its maximum height, the rocket deploys a parachute and then descends vertically to the ground. a. Determine the speed of the rocket after the 2 s firing of the engine. b. What maximum height will the rocket reach? с. At what time after t = 0 will the maximum height be reached?

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.
