Question

A 3.8 kg object is lifted 12 meters. approximately how much work is performed during the lifting.


A. 45.6 j

B. 588 j

C. 446.9 j

D. 372.4 j

Answer 1

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

Answer 2

Answer:

Explanation:

446.9 j
