Example 3.1 A robotic vehicle is exploring the surface of Mars. The stationary Mars lander is the origin of coordinates, and the surrounding surface lies in the xy-plane. The vehicle, which represents as a point, has the coordinates: x = 2.0 – 0.25t2 y = 1.0t + 0.025t3 a) Find the vehicle's coordinates and distance from the lander at t = 2.0s. b) Find the vehicle's displacement...
(2) Velocity Vectors Consider the curve given by the position vector: r(t) =< 3cos(t), 5sin(t), 4cos(t) > (2a) Find the velocity vector for this trajectory. (2b) Find the speed for a particle moving along this trajectory. (20) At what point (a,b,c) does the position vector pass through the xy-plane?
АЗ. You are given that the plane P contains both the point and the line Ls, where Q has position vec- tor q = i + 3, and L3 is given by the equation r = (0, i, 2) + λ(1, 3,-1) (where λ is a real parameter). i) Write down two vectors representing two different directions which lie in the plane P. [2 marks i) By using the cross product or otherwise, find a direction perpendicular to the plane....

Please double check my answers? If they're wrong can you explain how to do it right? My math book doesn't have examples for all of these scenarios and I really don't want to fail this assignment. I don't normally look for help online, but I'm kinda desperate. When I couldn't find a symbol for the exponent I used the ^ 1. 18r⁴ s⁵ t⁶ ÷ -3r² s t³ = ?
