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(8.8), the velocity of the object at time 

A. V(8.8) = 292.9 feet per second B. V(8.8) = 289.6 feet per second C. V(8.8) = 290.9 feet per second D. V(8.8) = 291.6 feet per second
