1.

a person carrying 10 bricks each of mass 2.5kg on his head moves to a height 20 m in 50s. Calculate power spent in carrying bricks by the person

Answer»

Power=Fs/t

F=mg=2.5×10×10=250

Power=Fs=(250×20)/50=100 Watt

We can use g=9.8 then ANSWER is little different.

then, F=2.5×10×9.8=245

Power=(245×20)/50=98 Watt
