While on a car trip of 1000 km, you travel half of the distance at 90 km/hr and the other half at 60 km/hr. On the return trip, you travel half the time at 90 km/hr and the other half at 60 km/hr. What is your average speed for the entire trip (in km/hr)?

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

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:

its a 5.5 n
