The acceleration of a body moving along a straight line is #(4-t) ms^2# and its velocity is v m/s after t seconds.
a).i) If the initial velocity of the body is 3m/s, express the velocity v in terms of t.
ii).Find the velocity of the body after 2 seconds.
b) Calculate:
i).The time taken to attain maximum velocity.
ii).The distance covered by the body to attain the maximum velocity.
