W = mgh.

m is mass in kg,

g is acceleration due to gravity = 9.81 m/s²,

h is height = 12 m

= 3.8 * 9.81 * 12

= 447.336 Joules

Alfredo · Answer 2

Work done is equivalent to potential energy.

W = mgh. m is mass in kg, g is acceleration due to gravity = 9.81 m/s², h is height = 12 m

= 3.8 * 9.81 * 12

= 447.336 Joules
