Question

Astronauts are testing the gravity on a new planet. A rock is dropped between two photogates that are 0.5 meters apart. The first photogate reads a velocity of 1.2 m/s and the the second photogate reads a velocity of 4.3 m/s . What is the acceleration of gravity on this new planet?

    Answer:

    a = 17 m / s²

    Explanation:

    For this experiment that the astronauts are carrying out, the value of the relation of gravity is cosecant, therefore we can use the kinematic relations

             v² = v₀² + 2a y

    They indicate the initial speed 1.2 m / s the final speed 4.3 m / s and the distance remembered 0.5 m

    we clear

            a = (v² – v₀²) / 2y

    we calculate

           a = (4.3² -1.2²) / 2 0.5

           a = 17 m / s²

    this is the gravity of the new planet
