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 480 feet. Show all steps in your work.

Answer 2

This one is just like the other one, I figured out the equation but I don't know how to plug in the numbers.

Answer 3

The formula is:
2d/t2 = g

Answer 4

Would the height = distance?

Answer 5

Nvm I got the answer of g = 9.6

Answer 6

Can anyone check that?

Answer 7

d = 0.5gt2 where

d = distance = 480 feet
g = the force of gravity,
t = time = 10 seconds

\[ d = \frac 12 gt^2 \]
\[ 480 = \frac 12 g \times 10^2 \]
\[ 480 = \frac 12 g \times 100 \]
\[ 480 = g \times \frac 12 \times 100 \]
\[ 480 = g \times 50 \]
\[ \frac{480}{50} = g \]

Answer 8

Where's your equation to solve for "g"?

Answer 9

Whatever, your answer is the same as mine.

Answer 10

yep, urs is perfect

Answer 11

Can you help me check another?

Answer 12

sure dude, shoot

Answer 13

Two boys want to use a seesaw and they need to move the seesaw so that their weights will balance out. The formula is given by w1 • d1 = w2 • d2 where w1 = weight of the first boy, d1 = distance of the first boy from the fulcrum, w2 = weight of the second boy, and d2 = distance of the second boy from the fulcrum. Rewrite the formula to solve for d2. Show all steps in your work.

Answer 14

My answer was w1 x d1/w2 = d2

Answer 15

yep, correct

Answer 16

Thanks.

Answer 17

welcomes dude
