Numerical

A weight lifted a load of 200 kgf to a height of 2.5 m in 5 s. calculate: (i) the work done, and (ii) the power developed by him. Take g= 10 N kg-1.

Solution

Given load m = 200kgf, displacement h = 25 m, time = 5s, g = 10 N kg-1

Now work done = 200 kgf x 25 = 50000 J

or power = `"work done"/"time taken" = 5000/5` = 1000 watt

  Is there an error in this question or solution?
