a bullet is shot downward out of a high building with an initial speed of 10 m/s . How fast is the bullet traveling after 5 seconds ( by m/s , neglect air friction , g = 9.8 m/s2)

50

Explanation:

yes

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.
