d is the total horizontal distance travelled by the projectile. v is the velocity at which the projectile is launched; g is the gravitational acceleration—usually taken to be 9.81 m/s 2 (32 f/s 2) near the Earth's surface; θ is the angle at which the projectile is launched; y 0 is the initial height of the projectile
Here, , and will be used to denote the initial velocity, the velocity along the direction of x and the velocity along the direction of y, respectively. The mass of the projectile will be denoted by m , and μ := k / m {\displaystyle \mu :=k/m} .
[15] [16] How much a projectile deviates from the applied reference projectile is mathematically expressed by the form factor (i). [17] The form factor can be used to compare the drag experienced by a projectile of interest to the drag experienced by the employed reference projectile at a given velocity (range).
Mathematically, it is given as = / where = acceleration due to gravity (app 9.81 m/s²), = initial velocity (m/s) and = angle made by the projectile with the horizontal axis. 2. Time of flight ( T {\displaystyle T} ): this is the total time taken for the projectile to fall back to the same plane from which it was projected.
To find the angle giving the maximum height for a given speed calculate the derivative of the maximum height = / with respect to , that is = / which is zero when = / =. So the maximum height H m a x = v 2 2 g {\displaystyle H_{\mathrm {max} }={v^{2} \over 2g}} is obtained when the projectile is fired straight up.
Projectile: Full metal projectiles should be made of a material with a very high density, like uranium (19.1 g/cm 3) or lead (11.3 g/cm 3).According to Newton's approximation, a full metal projectile made of uranium will pierce through roughly 2.5 times its own length of steel armor.
To calculate the velocity of the bullet given the horizontal swing, the following formula is used: [9] = where: is the velocity of the bullet, in feet per second; is the mass of the pendulum, in grains; is the mass of the bullet, in grains
Plot of trajectories of projectiles launched at different elevation angles but the same speed of 10 m/s in a vacuum and uniform downward gravity of 10 m/s^2; t = time from launch, T = time of flight, R = range and H = highest point of trajectory (indicated with arrows); points are at 0.05 s intervals and length of their tails is linearly ...
