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(5.6), the velocity of the object at time 
A. V(5.6) = 187.2 ft/sec B. V(5.6) = 188.5 ft/sec C. V(5.6) = 189.2 ft/sec D. V(5.6) = 190.5 ft/sec
