. Find the velocity in meters per second of a baseball thrown 38 m from third base to
first base in 1.7 seconds.

22.35m/s

Explanation:

Distance=38m

Time=1.7seconds

Velocity=distance ➗ time

Velocity=38 ➗ 1.7

Velocity=22.35m/s

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

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.
