Four second after starting from rest, what will be the velocity of an object in free fall?

Sagot :

The velocity of the object in free fall is 39.2 m/s.

Given the following data:

  • Initial velocity, U = 0 m/s (since the object is starting from rest).
  • Time, t = 4 seconds.

We know that acceleration due to gravity (a) for an object in free fall is equal to 9.8 meter per seconds square.

To find the final velocity (V) of the object, we would use the first equation of motion;

[tex]V = U + at\\\\V = 0 + 9.8(4)[/tex]

Final velocity, V = 39.2 m/s

Therefore, the velocity of the object in free fall is 39.2 m/s.
