Question

Suppose that a freely falling object were somehow equipped with an odometer. Would the readings of distance fallen each second indicate equal or different falling distances for successive seconds? 1. Greater distances fallen in successive seconds 2. All are wrong. 3. Smaller distances fallen in successive seconds 4. Equal distances fallen in successive seconds 5. Initially equal distances fallen in successive seconds, then greater distances fallen in successive seconds

Answer 1

Answer:

1  greater distances fallen in successive seconds

Explanation:

When a body falls freely it is subjected to the action of the force of gravity, which gives an acceleration of 9.8 m / s2, consequently, we are in an accelerated movement

If we use the kinematic formula we can find the position of the body

       Y = Vo t + ½ to t2

Where the initial velocity is zero or constant and the acceleration is the acceleration of gravity

Y = - ½ g t2 = - ½ 9.8 t2 = -4.9 t2

Let's look for the position for successive times

t (s)      Y (m)

  1          -4.9

  2         -19.6

   3        -43.2

The sign indicates that the positive sense is up

It can be clearly seen that the distance is greatly increased every second that passes
