Question

determine the work done by a man lifting weightsor 50kg to a height of 30m above the ground​

Answer 1

Answer:

15000 J

Explanation:

mass(m) = 50 kg

force(f) = mg

= 50 × 10

= 500N

distance(d) = 30m

Work done = f×d

=500×30

=15000 J

Note: If you take g = 9.8 m/s^2,the answer will be 14700J

Hope it helps !!
