Hello,

The following problem I worked out with this formula: V2=V1+gt. I came to the the answer 78.4 m/s.

Can you tell me if that is correct.
Thank You
If a stone with an original velocity of 0 is falling from a ledge and takes 8 seconds to hit the ground, What is the final velocity of the stone?

Yes, that is the correct formula to use, and the right numerical answer.

Sure! To verify if your answer is correct, I'll show you how to solve the problem using the given information and the formula you used.

The formula V2 = V1 + gt is the formula for calculating the final velocity (V2) of an object undergoing constant acceleration due to gravity. In this formula, V1 represents the initial velocity, g is the acceleration due to gravity (which is approximately 9.8 m/s² near the surface of the Earth), and t is the time.

In the problem, the stone has an initial velocity (V1) of 0 m/s as it falls from a ledge. The time (t) it takes for the stone to hit the ground is given as 8 seconds. We need to find the final velocity (V2) of the stone.

Plugging in the given values into the formula, we have:
V2 = V1 + gt
V2 = 0 + (9.8 m/s²)(8 s)
V2 = 0 + 78.4 m/s
V2 = 78.4 m/s

So, according to the equation and the values you provided, the correct answer for the final velocity of the stone is indeed 78.4 m/s.

If you obtained the same result using the same formula and the given information, then your answer of 78.4 m/s is correct.

Let me know if there's anything else I can help you with!
