Yes. take a bow for instance. while pulling back the string you have potential energy. when you let the string go and the arrow flies towards your target the string is filled with kinetic energy.

If you ran 15 km/h for 20 min, how much distance would you cover?

nikitadnepr [17]

Since we have 15 kilometers per hour, and we're looking for 20 minutes, let's set up proportions.
20/60 minutes = x/15
20/60 = 1/3, so let's leave that simplified.
1/3 = x/15
Look at the denominators, 3 to 15 is a factor of 5, so multiply the numerator by 5.
1 • 5 = 5, so you will cover 5 kilometers in 20 minutes.

I hope this helps!

a stone is dropped from top of a tower of 50m high ,simltaneously another stone is thrown upward with a speed of 20m/s find the

aleksklad [387]

At the time that I'll call ' Q ', the height of the stone that was
dropped from the tower is

 H = 50 - (1/2 G Q²) ,

and the height of the stone that was tossed straight up
from the ground is

 H = 20Q - (1/2 G Q²) .

The stones meet when them's heights are equal,
so that's the time when

 50 - (1/2 G Q²) = 20Q - (1/2 G Q²) .

This is looking like it's going to be easy.

Add (1/2 G Q²) to each side.
Then it says
 50 = 20Q

Divide each side by 20: 2.5 = Q .

And there we are. The stones pass each other

 2.5 seconds

after they are simultaneously launched.
