Question

A person mass 50 kg climbs a tower of height 72 meters. calculate the work done (g=9.8 m/s^-²

Answer 1

work=force×displacement
=50×9.8×72
=35280

Answer 2

$\textsf{\huge{\underline{Hello Mate!}}}$

So, work done = Force • displacement

Since, force = Mass • acceleration

Force = 50 kg • 9.8 m/s²

Force = 490 N

And displacement = 72 m

Work done = 490 N • 72 m

$\textsf{\red{Work done = 35280 J}}$
