Sita is driving along a staight highway in her car. At time t = 0, when Sita is moving at 10 ms^-1 in the positive x-direction, she passes a signpost at x = 50 m. Here acceleration is a function of time: a = 2.0 ms^-2 – (1/10 ms^-3)t a. Derive expressions for her velocity and position as functions of time. b. At what time is her velocity greatest? c. What is the maximum velocity? d. Where is the car when it reaches the maximum velocity?

At t = 0, a body starts from origin with some initial velocity. The displacement x(m) of the body varies with time t(s) as x = – (2/3)t^2 + 16t + 2. Find the initial velocity of the body and also find how long does the body take to come to rest? What is the acceleration of the body when it comes to rest?
