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

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

Step-by-step 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{(2h)/(g)}` ......................1

put here value and we will get here time that is

time =
`\sqrt{(2*1.60)/(9.81)}`

time = 0.5711 second

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