Question

Help !!! The distance traveled by a falling object is given by the formula d = 0.5gt^2 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

@bibby

Answer 2

d = 0.5gt^2

First step is to isolate g. That means dividing by 1/2 and t^2

Answer 3

2d/t^2=g

Answer 4

correct. and now we have the following info:

t=10 seconds
d = 490 ft

Answer 5

2(490)/10^2

Answer 6

980/100

Answer 7

9.8=g

Answer 8

or 9,8 (don't forget the units ft/s^2

Answer 9

9.8ft/s^2

Answer 10

Correct.

Answer 11

it might just be 9.8ft/s. I'm unsure on the units but the number is correct.
