WebTo use the formula for curvature, it is first necessary to express r(t) in terms of the arc-length parameter s, then find the unit tangent vector T(s) for the function r(s), then take the derivative of T(s) with respect to s. This is a tedious process. Fortunately, there are equivalent formulas for curvature. Theorem 3.6 WebThe position vector r describes the path of an object moving in the xy-plane. Position Vector: r (t) = 2 cos ti + 2 sin tj Point: (√2, √2) (c) Sketch a graph of the path, and sketch the velocity and acceleration vectors at the given point. Perform the indicated matrix operations. If the matrix does not exist, write impossible.

WebDec 20, 2024 · Solution. The acceleration vector of the enemy missile is. ae(t) = − 9.8ˆj. Integrating, we get the velocity vector. ve(t) = v1ˆi + (v2 − 9.8t)ˆj. Setting t = 0 and using the initial velocity of the enemy missile gives. ve(t) = − 30ˆi + (3 − 9.8t)ˆj. Now integrate again to find the position function.
