| The bullet flew horizontally from the muzzle at a speed of 1000 m / s. How much will the bullet’s height above the horizon change when it reaches the target at a distance of 750 m?
Given:
v = 1,000 m / s;
S = 750 meters.
Let’s start the solution by finding the time it takes for a bullet to travel 750 meters at a speed of 1,000 m / s.
Let’s apply the speed formula:
v = S / t;
Let us express the time from it and get:
t = S / v;
Substitute the values and calculate:
t = 750/1000 = 0.75 seconds.
Let us find the distance at which the bullet will fall in 0.75 seconds, under the influence of gravity.
We use the formula:
H = (g * t ^ 2) / 2;
g = 9.8 m / s.
We substitute the values into the formula and perform the calculation:
H = (9.8 * 0.75 ^ 2) / 2 = 2.75625 m.
