work=weigh*distance=10*g*2.5 Joules
force= 10g
height=work/weight=120/20 = 6 meters
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

I don't understand
1. F = M * g = 10 * 10 = 100 N.
Work = F * d = 100 * 2.5 = 250 Joules.
2. W = F*h.
120 = 20 * h.
h =
Work = F * d = 100 * 2.5 = 250 Joules.
2. W = F*h.
120 = 20 * h.
h =
