A potato is launched vertically upward with a velocity of +40.0 m/s from the edge of a cliff that is 50.0 m tall. Assume the potato leaves from the very edge of the cliff so it passes the cliff edge and falls to the ground of the nearby valley below. Answer each of the following neglecting air resistance. 8) Approximately how long is the potato airborne? (A) 5.1 sec (B) 7.9 sec (C) 8.33 sec (D) 9.26 sec (E) 14.7 sec 9) What is the approximate impact velocity of the potato the moment it strikes the ground below the cliff? (A) -9.81 m/sec (B) -26.4 m/sec (C) -33.5 m/sec (D) -42.7 m/sec (E) -50.8 m/sec 10) What is the maximum height above the ground below the cliff reached by the potato? (A) 8.16 x 10 m (B) 1.32 x 10- m (C) 6.41 x 10- m (D) 9.47 x 10- m (E) 1.32 x 103 m
