Arocket moves downwards with constant speed of 800 m/s along a parabolic path. the equation of the path is yy = 600 − xx2 121. when the rocket is at a point pp, the angle thetatheta measured counterclockwise from the to this point on the path is 60o. find: (a) the and coordinates of the point pp. (b) plot the path to scale (use matlab to do this). draw the normal and tangential unit vectors �⃗ and �⃗ at the point pp. what is the angle between the tangential unit vector �⃗ and the positive direction of the
