Question

an athelete weight 60 kg runs up a staircase having 10 steps eachnof 1 m in 30 sec calculate power g =9.8 ms

Answer 1

work done=mgh=60x9.8x10=5880J

power=work done/time=196 Watt

Answer 2

work done. = m× g×h

GIVEN.

MASS=60KG


H=1m×10=10m..


g=9 .8ms^-1

power=

$\frac{work \: \: done}{time}$



$= > \frac{m \times g \times h}{t}$

$= > \frac{60 \times 10 \times 9.8}{30s}$




$= > \frac{588 \times 100}{300}$



$= > 196$
