An object moves along a straight line with velocity v(t) = 3.0 sin(3t) metres/second, where t denotes the time in seconds. a. Given that its position at time t = 0 seconds is 2.0 metres, what is its displacement after t seconds? Displacement (as a function of t) = metres b. What is the object's acceleration after t seconds? Acceleration (as a function of t) = metres/seconds-squared
