Question

3)A soldier throws a grenade horizontally from the top of a cliff. Which of the following curves best describes the path taken by the grenade?

Parabola

4)A stone is thrown horizontally from the top of a 25.00-m cliff. The stone lands at a distance of 40.00 m from the edge of the cliff. What is the initial horizontal velocity of the stone?

15.60 m/s

Answer 1

3) parabola is correct

4) time of fall = sqrt (2H/g) = 2.26 s
horizontal travel = 40 = 2.26 * V
V = 17.7 m/s

Answer 2

3:
Parabola would be an acceptable choice.
