What is the average speed of a car that traveled 300.0 miles in 5.5 hours?
.

Average speed of the car is 54.55 miles/hour

Explanation:

The average speed of an object is the total distance traveled by the

object divided by the time taken to cover this distance

Speed is a scalar quantity which means it is defined only by magnitude

Average speed = total distance ÷ total time

A car traveled 300 miles in 5.5 hours

We need to find the average speed of the car

The average speed of the car = the distance traveled ÷ the time taken

for this distance

The distance is 300 miles

The time taken is 5.5 hours

Average speed = miles/hour

Average speed of the car is 54.55 miles/hour

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.
