A spacecraft moves along a path described by the parametric equations shown below for the first 100 s after launch. Here, x and y are measured in meters, and t is measured in seconds. Find th direction of the velocity of the spacecraft 10.0 s and 100 s after launch x -70 (1 1 +1- 1). y=601312 What would be the first step in finding the velocity of the spacecraft at a given time? O A. Differentiate y with respect to x. O B. Use the fact that distance = rate x time. O C. Differentiate the x- and y-position components to get the x- and y-velocity components. O D. Find the values of x and y for the given value of t. Find the magnitude of the velocity of the spacecraft when t = 10.0 s The magnitude is approximately m/s. ( Round to the nearest integer as needed.) Find the direction of the velocity of the spacecraft when t= 10.0 s. Enter an angle 0 such that 0 = 0
