The acceleration of an object in motion is given by a = 2-6t,where t is time in seconds after the object passes a fixed point O.
a).Given that the initial velocity is 8m/s ,express the velocity V in terms of t.
b).Determine the time the object is momentarily at rest.
c).i).Write down an expression for the displacement S metres from the fixed point O after t seconds.
ii).Calculate the displacement of the object from O after 2 seconds.
d).Determine the maximum velocity attained by the object.
