)The formula for calculating initial velocity of a projectile is: v0 = √(g * h) where v0 is the initial velocity, g is the acceleration due to gravity, and h is the height of the projectile.
The units for v0 will be in meters per second (m/s), g will be in meters per second squared (m/s^2), and h will be in meters (m). It is important to use consistent units throughout the calculation to ensure accurate results.
Yes, the initial velocity of a projectile can be negative if it is launched at an angle below the horizontal. This indicates that the projectile is moving downward at the beginning of its trajectory. However, in most cases, the initial velocity is assumed to be positive as the projectile is launched upward.
Air resistance can decrease the initial velocity of a projectile. As the projectile moves through the air, it experiences air resistance which acts in the opposite direction of its motion. This resistance can slow down the projectile and affect its initial velocity. To account for air resistance, a more complex formula is needed to calculate the initial velocity.
Other factors that can affect the initial velocity of a projectile include the angle at which it is launched, the mass of the projectile, and any external forces acting on the projectile (such as wind or friction). These factors can influence the acceleration and trajectory of the projectile, ultimately affecting its initial velocity.
