An athlete runs 600 m in 2 minutes and the next 1000 m in 1 minute on the same straight path. What is his average speed and average velocity?​

Explanation:

Average speed is found by adding together the total distances traveled by the athlete and divide that total by the total time it took.

Average velocity is vector, which means it includes direction. If the athlete heads one way and then turns around, his displacement might actually be negative! Yikes! Let's look at speed first:

Velocity is the displacements added together divided by the total amount of time it took. The displacement is the same as the distance here, since the athlete did not veer off his straight-path and didn't turn around.

Average velocity = average speed = 533.3 m/min

the answer would be   dignified - apex

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.
