Question

I solved a problem but I need help checking it.
Problem:The distance traveled by a falling object is given by the formula d = 0.5gt2 where d = distance, g = the acceleration due to gravity, and t = time. Solve this equation for g, and use your formula to determine the acceleration due to gravity if a baseball takes 10 seconds to hit the ground after being dropped from a height of 490 meters.

Answer 1

My answer : The formula I will be using is d over .5t^2 = g.
I will first fill in the variables with the numbers that is given. The equation is now 490 over .5(10)^2=g. The second thing I need to do is multiply .5 by ten, which gives me 5. Then I multiply 5 by 5, because the exponent is 2, and that gives me 25. That leaves the equation as 490 over 25 = g. The last step is to divide 490 by 25, which gives me 19.6. So 19.6=g.
