Clarifications. Although you can contribute to a Roth IRA during your retirement years, you cannot contribute unlimited amounts of money. The IRS enforces contribution limits for traditional and Roth IRAs regardless of age. In 2010, for example, you could contribute $6,000 if you are older than 50.
The formula for determining the velocity of a falling object after a time of t seconds is vf = g * t (dropped from rest) where g is the acceleration of gravity. The value for g on Earth is 9.8 m/s/s. The above equation can be used to calculate the velocity of the object after any given amount of time when dropped from rest. Example calculations for the velocity of a free-falling object after six and eight seconds are shown below. Example Calculations:
It is the gravitational attraction between the Earth and the object that accelerates the object towards the Eart â¦ h, which is basically what falling is. Gravity on Earth accelerates things at about 9.81 meters per second Hope this helps!
