Question

An object is projected straight upward neglecting air resistance it ….A.)Has a constant acceleration throughout B.)Returns with the same speed C.)Has all the above

Answer 1

Step-by-step explanation

Step 1

Diagram

so

Vertical motion is the movement of an object in a straight line. When an object is thrown up, it always comes down, as it is affected by the acceleration due to gravity.thus, the only acceleration is due to gravity, when going up, the acceleration due to gravity " desacelerates the object " and a constant rate, al

so,it has a constant acceleration

also, the law of conservation of energy states that the amount of energy is neither created nor destroyed,so after the object reaches it s maximum heigth the gravitational potential energy is converted to kinetic energy when the mass moves downward,as there is not resistance it, the kinetick energy will be the same, becuase

`Kinetic\text{ energy=}(1)/(2)mv^2`

and the mass , and the
