Calculate the work needed to lift a block weighing 4 Newton’s a distance of 10 meters. Help me please.

W = 40 J

Explanation:

The work done by a force is defined as the dot product of the force and displacement of the object. Therefore, the following formula can be used to find the work done:

where,

W = Work Done = ?

F = Force = Weight of Block = 4 N

d = distance lifted = 10 m

θ = angle between force and displacement = 0°

Therefore,

W = 40 J

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.

force tends to be low and long diustance masses are high
