The problem involves finding the velocity and acceleration of a mass in simple harmonic motion, described by the equation of motion x = (0.2m) sin (3t). The specific condition is to determine these quantities when the object is +5cm from its equilibrium position.
The discussion is ongoing, with participants seeking clarification on how to apply calculus to derive the necessary expressions. Some guidance has been provided regarding the differentiation process, but there is no explicit consensus on the next steps.
Participants express uncertainty about the statement of the problem and the calculations involved, indicating a need for further clarification on the definitions and applications of velocity and acceleration in this context.
Exactly. So find expressions for v and a. Then combine them with the expression for x.vooov92 said:how??
for v i use dx/dt
for a i use dv/dt
