A student has an object with a mass of 8.0 kg8.0\text{ kg}8.0 kg.
Calculate the weight of the object. (Take the gravitational field strength g=10 N/kgg = 10\text{ N/kg}g=10 N/kg)
The student lifts the 8.0 kg8.0\text{ kg}8.0 kg object from the floor onto a table. They do 120 J120\text{ J}120 J of work on the object in lifting it onto the table.
State the amount of gravitational potential energy gained by the object due to being lifted onto the table.
The weight of a table is 360 N360\text{ N}360 N. The table has four legs. The area of each table leg in contact with the floor is 15 cm215\text{ cm}^215 cm2.
Calculate the pressure of the table on the floor. Give the correct unit.
