The Velocity V(t) (T)= X'(t) at Time T of an Object

Short Answer

The velocity v(t) (t)= x'(t) at time t of an object moving along the x axis is given, along with the initial position x(0) of the object. $x ^ { t } ( t ) = - 4 ( 3 t + 1 ) ^ { 1 / 2 }$ ; x(0) = 4
Find: (a) The position x(t) at time t.
(b) The position of the object at time t = 6.
(c) The time when the object is at x = 1.Round answers for parts (b) and (c) to one decimal place.
