Jon is standing on a bridge over a creek. he releases a stone 20 feet from the water. how long will it take the stone to hit the water?

The distance covered by a free-falling object in 'T' seconds after it's dropped is

D = (1/2) x (gravity acceleration) x (T²)

Gravity acceleration on Earth is 9.8 m/s². or 32.2 feet/sec² .

20-ft = (1/2) (16.1) (T²)

20 = 8.05 T²

T = √(20/8.05) = 1.576 seconds .

The correct option is B) Figure QRTS is congruent to figure Q’R’TS’. But reflected about the y axis.

Step-by-step explanation:

Consider the provided information,

Now, draw the quadrilaterals with the help of provided information.

The figure 1 shows the two quadrilaterals.

Now, consider the provided options.

Option A is wrong because QRTS is not bigger than figure Q’R’T’S.

Option B is correct because Figure QRTS is congruent to figure Q’R’TS’. But reflected about the y axis.

Option C is wrong because measure of angle R is not equal to the measure of angle Q’. Measure of angle R is equal to the measure of angle R’.

Option D is wrong because the measure of angle S is not equal to the measure of angle T’. The measure of angle S is equal to the measure of angle S’.

Hence, the correct option is B) Figure QRTS is congruent to figure Q’R’TS’. But reflected about the y axis.
