Final answer:
The velocity of a particle expressed as v(t) = sin(πt/2) is found by differentiating the position function, resulting in v(t) = (π/2)cos(πt/2), which gives the velocity at any time t.
Step-by-step explanation:
The velocity of a particle is given by the equation v(t) = sin(πt/2). To find the velocity at time t, we need to take the derivative of the position function s with respect to time t.
Velocity is the first derivative of position. Using the chain rule for the derivative of the sine function, we have:
v(t) = d/dt[sin(πt/2)]
= (π/2)cos(πt/2)
This equation gives us the velocity v(t) of the particle at any time t.
