caclulate the force applied to move a bag of 10kg through a vertical distance of 2.5m.if (g=10m/s) also determine the work done

if a work of 120j is done by moving a box of weight 20N through a vertical height. calculate the height

plz help I can't solve them in textbook
Answered by bobpursley
work=weigh*distance=10*g*2.5 Joules
force= 10g

height=work/weight=120/20 = 6 meters

2. W = F*h.
120 = 20 * h.
h =
