Question

please solve this problem ​

Answer 1

Hello.

Answer:

The correct answer is 50 W.

Explanation:

Formula of Power = Work / Time

Work = Force* displacement

Therefore , first we calculate the work done.

• Acceleration due to gravity =10m/s^2

Work = 5*10*10

Work = 500J

Power = 500J/10s

Power=50W

Thank you.

Hope it helps

Answer 2

Answer:

49 Watts (if g=9.8ms^-2)

Explanation:

The problem is easy.... since Rohan is applying force under gravity's influence, the formula for power will be

$p = \frac{work}{time}$

$= \frac{force \: \times displacement}{time}$

$= \frac{mg \times h}{t}$

=5×9.8×10/10

=49W
