An object at rest falls from a height of 65.0 m. It attains its terminal velocity after it had traveled 25.0 m. Neglecting air resistance, its terminal velocity is found to be 75 percent of its supposed velocity just before it hits the ground. (a) Find the terminal velocity of the body. (b) How long does it take, after reaching its terminal velocity, to reach the ground? Assume Vewton's law of resistance holds.
