				   The position of a particle is given by x = A cos (wt + @), where w, and @ are constants. Find velocity at any time t.

7 years ago


Answers : (1)



x = A cos(wt + @)

Now, velocity is defined as dx/dt

this means that to get the velocity, we will have to differentiate the term on the right side :

A = constant

d(cos at)/dt = -a sin at

This implies v = -Aw sin (wt + @)
