Question

A particle moves along the x-axis so that at any time t, measured in seconds, its position is given by s(t) = 4sin(t) - cos(2t), measured in feet. What is the acceleration of the particle at time t = 0 seconds?

Answer 3

What is the acceleration of the particle at time t = 0 seconds?
It says that you need to have the acceleration equation given, you get it by taking the second derivative of the position equation s(t) = 4sin(t) - cos(2t). After that, it says to plug 0 to t (t=0) to the acceleration (second derivative equation)
