A3.8 kg object is lifted 12 meters. approximately how much work is performed during the lifting. a. 45.6 jb. 588 jc. 446.9 jd. 372.4 j

work done=446.9 J . so option (c) is correct.

Explanation:

the formula for work done is given by

W= F d

F= force= mg where m= mass and g= acceleration due to gravity

F= 3.8 (9.8)=37.24 J

so W=37.24 (12)

W=446.9 J

pretty sure it's false

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
