A bullet is fired from a rifle with speed v 0 at an angle Î¸ with respect

Question:

A bullet is fired from a rifle with speed v₀at an angle Î¸ with respect to the horizontal axis (Fig. P4.32) from a cliff that is a height h above the ground below.

(a) Calculate the speed of the bullet when it strikes the ground. Express your answer in terms of v₀, h, g, and Î¸.

(b) Explain why your result is independent of Î¸.
