What is the mass of a block if it's moving at 10 m/s and has 200 J of energy

4 Kg

Explanation:

K.E=1/2 m v2

200=1/2 m (10)2

200=1/2 m 100

200=m * 50

m=200/50

m=4 Kg

would be false hope this out

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.
