A spacecraft moves along a path described by the parametric equations shown below for the first 300 s after launch. Here, x and y are measured in meters, and I is measured in seconds Find the magnitude and direction of the velocity of the spacecraft 30.0 s and 300 s after launch x=20 (1+1' -1). y=6013/2 What would be the first step in finding the velocity of the spacecraft at a given time? O A. Use the fact that distance = rate x time. O B. Differentiate the x- and y-position components to get the x- and y-velocity components O C. Differentiate y with respect to x. D. Find the values of x and y for the given value of t Question Viewer Find the magnitude of the velocity of the spacecraft when t = 30 0 s The magnitude is approximatelymis (Round to the nearest integer as needed ) Find the direction of the velocity of the spacecraft when ! = 30.0 s. Enter an angle ( such that 0' s0
