Step 1
Step 1: We can use the following equation to find the time it takes for the bullet to hit the ground: $$t = \frac{v_f - v_i}{a}$$ where: * $t$ is the time * $v_f$ is the final velocity * $v_i$ is the initial velocity * $a$ is the acceleration due to gravity Show more…

On New Year's Eve, a stupid person fires a pistol straight up. The bullet leaves the gun at a speed of $100 \mathrm{~m} / \mathrm{s}$. How long does it take before the bullet hits the ground?
Before working this problem, review Conceptual Example $15 .$ A pellet gun is fired straight downward from the edge of a cliff that is 15 $\mathrm{m}$ above the ground. The pellet strikes the ground with a speed of 27 $\mathrm{m} / \mathrm{s}$ . How far above the cliff edge would the pellet have gone had the gun been fired straight upward?
2. The muzzle velocity of a bullet fired from a new rifle is 100 m/s. Neglecting air resistance, how far will a bullet fired straight down in the air have traveled at the end of one second ? 3. A pot falls from a ledge, how fast will it be traveling if it hits the ground 45m below?
