If you drop a rock from a height of 13 m, it accelerates at 9.8 m/s2
and strikes the ground
1.62882 s later.
If you drop the same rock from half that
height, what will be its acceleration?
1. the same.
2. about half.
3. Unable to determine.
4. more.
5. 0.

Unable to determine is the answer

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.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
