Answer to Question #280098 in Molecular Physics | Thermodynamics for mela

Question

Calculation of the instantaneous velocity at a specific time,given x is in meters and t is in seconds.

Calculate the instantaneous velocity of the object at time t=3s

Answer 1

Instantaneous velocity is given by, $v=dx/dt$

So when given the equation for the position of the object, find its derivative with respect to time t after which you substitute for the value of t given like in this case, t=3s.
