A 60 kg skydiver moving at terminal speed 40 m in 2 seconds. The sky diver is spending a power of
___ KW.

Open in App

Solution

Power spent by the skydiver = $\frac{w o r k d o n e}{t i m e}$

Work done in 2 seconds = Force x Displacement
$= (60 \times 10 \times 40) J$
So, power spent in 2 seconds $= (60 \times 10 \times \frac{40}{2}) W$

$= 12000 W$

$= 12 K W$
