A hot-air balloon is rising vertically with a constant velocity of 10 m/sec. An object is
dropped from the balloon when it is 60 m above the ground. The angle of elevation of
the Sun is 45o. When the falling object is 33.75 m from the ground, the rate at which
the shadow of the object is traveling along the ground is (take g = 10 m/sec2)
(A) 15 m/sec. (B) 20 m/sec. (C) 25 m/sec. (D) 30 m/sec.
