Question

Consider a projectile that is launched horizontally from a fixed height above the ground. Ignore air resistance. Does the time of flight for the projectile depend on the initial height? Yes or no: Does the time of flight for the projectile depend on the initial velocity? Yes or no: Does the distance that the projectile lands from the initial launch site depend on initial velocity? Yes or no: As the projectile travels through the air, does the horizontal component of the velocity increase, decrease, or stay the same? As the projectile travels through the air, does the vertical component of the velocity increase, decrease, or stay the same?

Explanation / Answer

1. Yes the time of flight depend on the initial height. 2.No the time of flight doesnt depends on the initial velocity. 3.Yes the distance that the projectile lands from the initial launch depends on initial velocity. 4.Horizontal component of the velocity remains same as there is no acceleration in horizontal direction. 5.Vertical velocity will increase because of gravitational force in vertical direction.
