Problem
The position of a particle moving along a straight line is s = (0.40 sin(0.80 t)) m, where t is in seconds and the argument of the sine function is in radians. Determine the velocity and acceleration at t = 2.5 s, and determine the smallest t > 0 at which the particle is instantaneously at rest.
Hint
Differentiate the given s(t) with the chain rule; keep the 0.80 t argument in radians.
