I think that in order for work to be done, the object must move in the direction of the force and move over a distance.
Explanation:
answer is attached, kindly see answer
The horizontal velocity<span> of a projectile is </span>constant<span> (a never </span>changing<span> in value), There is a </span>vertical<span>acceleration caused by gravity; its value is 9.8 m/s/s, down, The </span>vertical velocity<span> of a projectile </span>changes<span> by 9.8 m/s each second, The </span>horizontal<span> motion of a projectile is independent of its </span>vertical<span> motion.</span>
Use the impulse-momentum theorem.
Substitute your known values:
Hope this helps!
