If a laptop of mass 1.4 kg is lifted to a table of height 0.8 m, how much gravitational potential energy is added to the laptop?

Potential Energy = mgh , 

mass = 1.4 kg, g ≈ 10 m/s², h = 0.8m

Potential Energy = mgh = 1.4 * 10 * 0.8 = 11.2 N

Potential Energy added = 11.2 N

To calculate Potential Energy you need to Multiply 1.4*.8*9.8.... 9.8 is the acceleration due to gravity an they expect you to know to add 9.8 when you calculate Potential Energy. So the correct answer is 10.976 but rounded up is 11.
