A speed versus time graph shown: 15.
Which statement accurately describes the motion of the object in the graph above?

It is moving from os to 4 s at a constant speed of 2 cm/s.

It is at rest for 4 seconds from 4s to 8 s and then speeds up.

It is moving from 4 s to 8 s at constant speed of 4 cm/

It is speeding up from O s to 4 s then it is at rest.

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.

given values:

mass = 0.3 kg.

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
