Review the example on page 111 of your textbook for calculating the average speed for a day long bus trip. In the example, the time spent at each of the cities is included in the calculation. However, the bus driver wants to know his average driving speed not counting the stops. To find this information, recalculate the average speed omitting the time spent at the stops. What was the average speed while the bus was in motion?

the device is called “ rocket engine”

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.

given values:

mass = 0.3 kg.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
