Question

Consider a graphical representation (figure) of simple harmonic motion as described mathematically in equation X(t) = A cos(wt + €). When the particle is at point on the graph, what can you say about its position and velocity? The position and velocity are both positive. The position is positive, and the velocity is zero. The position and velocity are both negative. The position is negative, and the velocity is zero. The position is positive, and the velocity is negative. The position is negative, and the velocity is positive.

Answer 1

Simole han manta mohion shown above at paint A posohan is negative IV -- Aw? Since A in ve : V = +ve So Velocity is positive posolian is negative and velocity to positive. The position and velocity are both positive. The position is positive, and the velocity is zero. The position and velocity are both negative. The position is negative, and the velocity is zero. The position is positive, and the velocity is negative. The position is negative, and the velocity is positive.
