Trajectory

Maximum Height

Time of flight

The initial velocity of the projectile

The initial horizontal velocity of the projectile

None of the above

g

Viy

Vix

Behind the plane, because the projectile moves backward

Directly below it

In front of the plane

Behind the plane, because the projectile moves straight down

The ball will go backwards

The ball will go forward

The ball will drop straight down

None of the above

It is constant throughout the projectile

It is 0 at the top of the motion

= 9.8 m/s/s

It depends on the problem, we cannot assume anything until we see the problem

Horizontal

Flat Surface

Non Flat Surface

Projectile out of a Moving Object (an air plane)

It is a combination of Vix and Viy through Pythagorean theorem

Vi = Vf, they are just in the opposite direction

It is upward and to the right unless stated otherwise

All of the above

You can solve it using the h(max) equation

It occurs at the exact halfway point of the total time of the projectile

It occurs when the vertical velocity is 0

All of the above

$Vix\times t=\Delta x$

$v_f^2\ =v_i^2\ +2a\Delta x$

$Vix\times\Delta x=t$

$\Delta x=\frac{1}{2}at^2$
