An object is moving 10 in a negative direction and has -18kg*m/s of momentum. What is the objects mass in kg? Round your answer to the nearest hundredth (two decimal places).

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.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
