Question

Ethan carried a 200 Newton bag 3 meters up a ladder in 30 seconds. How much power did he use?

Answer 1

Answer:

$power = \frac{work done}{time}$

Power= (200×3)/30=20W

Answer 2

Step-by-step explanation:

Force = 200N

Displacement= 3 m

Time taken = 30s

power= ?

$power = \frac{workdone}{time} = \frac{force \times displacement}{time}$

$\frac{200 \times 3}{30} = 20$

Ethan use 20w power to carry a bag
