What is the horizontal acceleration of a ball that is launched horizontally with a velocity of 5.6 m/s?

Explanation:

When an object is launched under the action of gravity, the path followed by it is called projectile motion. The horizontal component of velocity is given by :

is the angle made with horizontal

In case of projectile motion, the velocity of projectile is constant in horizontal direction. As a result the rate of change of velocity will be equal to 0. So, the horizontal acceleration of a ball that is launched horizontally is 0. Hence, this is the required solution.

it would be kevlar ^^

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
