FIGURE 4.4 shows three objects A, B and C are kept in static equilibrium. The mass of B is 2.0 kg. Object A is just about to slide on the table. The coefficient of static friction between A and the horizontal table is 0.30. Calculate the
(a) mass of C = 2.83 kg
(b) mass of A = 6.67 kg

Help me out please, i want to cry.. the answer is already given. But i want to know the working

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.
