Three point masses of 2kg each are located on the x-axis at the origin, at x=0.20m, and at x=0.50m. Find the center of mass of the system? 25. A 15g bullet traveling at 500m/s strikes an 0.8 kg block of wood that is balanced on the table edge 0.8m above the ground . If the bullet buries itself in the block. Find the distance D at which the block hits the floor?

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.
