Problem 4. Given a curve C, the vectors T(t), N(t), and B(t) form a special coordinate system (called an orthonormal reference frame) that lets us discuss velocity and acceleration of a moving object from the perspective of the object itself. (Consider, for example, looking only at the motion of an airplane to study its stability without worrying about its position relative to its starting point.) (a) Use the fact that v uT, where u(t)-|r(t)l is the speed of the particle,...
(1 point) A stone is thrown from a rooftop at time t 0 seconds. Its position at time t (the components are measured in meters) is given by r()-бі-50+ (24.5-49:2) k. The origin is at the base of the bulding, which is standing on flat ground. Distance is measured in meters. The vector i points east,j points north, and k points up. (a) How high is the rooftop? meters. (b) When does the stone hit the ground? seconds (c) Where...
