Question

A bullet is fired from a rifle that is held 1.60 m above the ground in a horizontal position. The initial speed of the bullet is 1058 m/s. Calculate the time it takes for the bullet to strike the ground.

Answer 1

Answer:

time takes for the bullet to strike the ground is 0.5711 second

Explanation:

given data

height h = 1.60 m

initial speed u = 1058 m/s

solution

we get here time that is express here as

time = $\sqrt{\frac{2h}{g}}$     ......................1

put here value and we will get here time that is

time = $\sqrt{\frac{2*1.60}{9.81}}$

time = 0.5711 second

so time takes for the bullet to strike the ground is 0.5711 second
