Work against gravity is mgh, independent of horizontal distance

Steps:

• Gravitational force = mass × g = 60 kg × 9.8 m/s² = 588 N
• Relevant displacement is vertical height h = 1.5 m
• Work done = force × h = 588 N × 1.5 m = 882 J
• This approximates to 880 J, matching option C

Why C is correct:

• Equals gain in gravitational potential energy mgh, per work-energy principle

Why the others are wrong:

• A. Too small; ignores multiplication by g (uses mh only)
• B. Incorrect partial calculation; no clear basis
• D. Overestimates by including horizontal distance (e.g., mg × total path)

Final answer: C
