If you apply 1 J of energy to lift a book of 0.5 kg, how high will it rise?

Solution

$Given space that comma space Potential space energy comma space straight P. straight E. space equals space 1 space straight J Mass space of space the space body comma space space straight m space equals space 0.5 space kg Acceleration space due space to space gravity comma space straight g space equals space 10 space straight m divided by straight s squared Height comma space space straight h space equals space ? Using space the space formula comma space space space space space space space space space space space straight P. straight E. space equals space mgh space space therefore space space space space space 1 space equals space 0.5 space cross times space 10 space cross times space straight h rightwards double arrow space space space space space space straight h space equals space fraction numerator 1 over denominator 0.5 space cross times space 10 end fraction space space space space space space space space space space space space space space equals space space 0.2 space straight m space space space space space space space space space space space space space space space equals space 20 space cm Thus space the space book space will space rise space to space straight a space height space straight f space 20 space cm$
