Question

A man pulls a block with a force of 200n through 50m in 1 minute.find the power used by him to pull the block

Answer 1

Answer:

P   =   WD                               WD  =   Force  x  Distance

           T                                         =   200 N  x  50 m

    =   10 x 10^3 N/m                      =    10 x 10^3 N/m      

                60

    =   166.67 Watts

Answer 2

$\Large{\textbf{\underline{\underline{According\;to\;the\;Question}}}}$

Information :-

Force(F) = 200 N

Displacement(s) = 50 m

Time(t) = 1 min

Convert 1 min into second :-

= 1 × 60

= 60 seconds

As we know that :-

Work done(W•d)

= F × s

= 200 × 50

= 10000 Joule

Also,

We know that,

Power = Work done/Time

= 10000/60

= 166.67 Watt
