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(7.5), the velocity of the object at time 

A. V(7.5) = 250 ft per sec B. V(7.5) = 251.3 ft per sec C. V(7.5) = 248 ft per sec D. V(7.5) = 249.3 ft per sec
