Solve the problem. Approximate to the nearest tenth when necessary.The velocity v, in ft/s, of a free-falling object after t seconds is given by the formula v = 32t until the object reaches terminal velocity. The terminal velocity Vt of a free-falling object is the highest velocity that the object can attain, and it depends on the mass of the object as well as its projected area. The distance d, in feet, that a free-falling object falls in t seconds is given by the formula 
until it reaches terminal velocity. After that occurs, the distance that it falls is found by multiplying the terminal velocity Vt by the amount of time after it reaches terminal velocity. Find the
