An asteroid has position ra(t) = R(cos(t/to), sin(t/to), 0) as a function of time t, where R and to are constants. An unmanned space probe is programmed to move at constant speed along a straight line that intercepts the comet at time t = 7to, with perfectly matched velocity (to avoid a damaging collision). Find the time-dependent position r(t) of the probe.

Question
An asteroid has position ra(t)= R (cos(t/to), sin(t/to), 0) as a function of time t, where R and to are constants. An unmanned space probe is programmed to move at constant speed along a straight line that intercepts the comet at time t = to, with perfectly matched velocity (to avoid a damaging collision). Find the time-dependent position r(t) of the probe. 2. In this question, submit hand-drawn sketches only. Computer-generated or Al-assisted sketches will receive zero marks. (a) Using contours, sketch the scalar field f(r) = 1/(xy) in the (x, y)-plane. Sketch and label enough contours to make the form of the field clear. (b) Using arrows, clearly sketch the vector field u(r) = (y², x+y, 0) in the (x, y)-plane.
