What is the power output of an electric motor
that lifts a 2.0-kilogram block 15 meters
vertically in 6.0 seconds?
(1) 5.0 j (3) 49 j
(2) 5.0 w (4) 49 w

Mass of the block = 2.0 kg
Value of gravity = 9.81 m/s^2
Distance upto which the mass is lifted = 15 meters
Time taken to lift the mass of the block = 6.0 seconds
Now we already know
Work Done = Mass * Gravity * Distance
                   = 2 * 9.81 * 15
                   = 294 Joules
Then
Power Output = Work Done/Time
                       = 294/6
                       = 49 Watts
So the power output of the electric motor is 49 watts.The correct option among all the options given in the question is option "4".

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d

Ibelieve the answer is arteries
