You used 950 j of work to push a sofa if it took you 5 s to move the sofa what was your power?

Explanation:

Given

Work (W) = 950 J

time (t) = 5 sec

Power (P) = ?

We know

p = w/t

= 950/5

= 190 watt

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.
