Question

. An object falls a distance H in 50 s when dropped on the surface of the earth. How long would it
take for the same object to fall through the same distance on the surface of a planet whose mass
and radius are twice that of the earth?​

Answer 1

Answer:

Explanation:

Determine the gravitational acceleration. ...

Decide whether the object has an initial velocity. ...

Choose how long the object is falling. ...

Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + g * t = 0 + 9.80665 * 8 = 78.45 m/s .
