Which situation would require the most work? a) 20 kg weight lifted 6 m b) 25 kg weight lifted 3 m c) 25 kg weight lifted 6 m d) 50 kg weight lifted 1 m

Work= force (N) x distance (m)

F= mass (kg) x acceleration (gravity; m/s^2)

for this question, your formula would be

Work= mass (kg) x acceleration (gravity) x distance (m)

a. F=20kg x 9.81 m/s^2 x6 m = 1177.2 J

b. F=25kg x 9.81 m/s^2 x3 m = 735.75 J

c. F=25kg x 9.81 m/s^2 x6 m = 1471.5 J

d. F=50kg x 9.81 m/s^2 x1 m = 490.5 J

Tip:

he kicked it 10 feet straight up into the air? i think this works.

the correct choice is a .
