An object is released from rest at time t = 0 and falls through the air, which exerts a resistive force such that the acceleration a of the object is given by a = g bv, where v is the object's speed and b is a constant. if limiting cases for large and small values of t are considered, which of the following is a possible expression for the speed of the object as an explicit function of time? a) v = g(1-e^-bt)/b b) v = (ge^bt)/b c) v = (g+a)t/b
