Question

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 feet. Show all steps in your work. Pleaseee help c:

Answer 1

\[d=\frac{ g t ^{2} }{ 2 }\]

First multiply both sides of the equation by 2

The divide both sides of the new equation by t^2

Answer 2

or u can divide by 0.5t^2 and get g=d/0.5t^2

Answer 3

So d/0.5t^2=g?

Answer 4

@AntonioCochrane
OR you could let the OP do some work for herself....

Answer 5

lol.sure

Answer 6

ookay xD

Answer 7

ya

Answer 8

so oyu have the formula for g

put the numbers in from the question - you can then calculate g

Answer 9

um thats it

Answer 10

g=9.8ft/sec?

Answer 11

It seems that this is the correct answer to this question

490/0.5*10^2 =490/50 = 9.8.

PLEASE NOTE TWO THINGS
First the units are ft/s^2 not ft/s

SECOND - this is NOT the correct value for g on earth - I believe the questioner has got units wrong. IF the question had said 490m (not ft) then the answer of 9.8 m/s^s IS correct value for g on earth.

Answer 12

Thank you so much!

Answer 13

u get it now
