Solve the problem.If an object is dropped from a tower, then the velocity, V (in feet per second), of the object after t seconds can be obtained by multiplying t by 32 and adding 10 to the result. Find V as a linear function of t, and use this function to evaluate V(3.1), the velocity of the object at time 
A. V(3.1) = 107.2 ft/sec B. V(3.1) = 108.5 ft/sec C. V(3.1) = 109.2 ft/sec D. V(3.1) = 110.5 ft/sec
