After a projectile is fired into the air, what is the acceleration in the x-direction? (assume no air resistance.)

Explanation:

When projectile is in air then the force on the projectile is only due to its weight

It is vertically downwards

so here since we don't have any air drag or friction due to air so there will be no force along its tangent or along x direction

so the acceleration along x direction will be zero

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

unbalanced force
