Robebobeccoba fires a bullet from a gun while aiming at a target 149 m away. if the

bullet misses the target by 1 m, what is the horizontal velocity of the bullet?

329.6 m/s

Explanation:

The bullet has a projectile motion, consisting of two separate motions:

- A horizontal motion with constant velocity

- A free fall motion (constant acceleration) in the vertical direction

The bullet misses the target vertically by 1 m: this means that 1 m is the vertical dispalcement of the bullet. So we can find the total time of the flight by using the suvat equation

where

s = 1 m is the vertical displacement

u = 0 is the initial vertical velocity

is the acceleration due to gravity

t is the time

Solving for t,

The horizontal motion is at constant speed, which is given by

where

d = 149 m is the distance covered by the bullet

t = 0.452 s is the time taken

Substituting,

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
