you see a bolt of lightning and hear thunder two seconds later. the speed of sound is about 343 m/s. estimate your distance from the lightning bolt?
600 m
1,800 m
10 m
40,000 m

600 m

Explanation:

Speed is defined as the distance traveled in a especific time :  

Where:  

is the speed of sound  

the time you hear the thunder after you see the flash of lightning  

We need to find the distance at which you are from the lightning strike:  

Finding :  

Finally:  

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
