Question

2. The distance traveled by a falling object is given by the formula d = 0.5gt2 where d = distance, g = the force of gravity, and t = time. Solve this equation for g, and use your formula to determine the force of gravity if a baseball takes 10 seconds to hit the ground after being dropped from a height of 490 feet. Show all steps in your work.

Answer 1

it's t2

Answer 2

\[g=\frac{ d }{ 0.1t }\]

Answer 3

I'm sorry my mistake It was t^2

Answer 4

ok so...\[g=\frac{ d }{ 0.5t^2 }\]

Answer 5

okay so

Answer 6

now just plug in values for d,490, and t, 10

Answer 7

\[g=\frac{ 490 }{ .05(10)^2 }\]

Answer 8

9.8?

Answer 9

or 50?

Answer 10

\[g=\frac{ 490 }{ 5 }=98\]

Answer 11

yes, 98 ft/sec

Answer 12

thanks!

Answer 13

sure!
