A weight lifter performs a clean and jerk on 150 kg, raising it 2 m above the ground in 1.5 s. What is his power output during the lift?

M g H/t = 150*9.8*2.0/1.5 = ___ watts

To calculate the power output during the lift, you need to use the formula:

Power = Work / Time

First, we need to calculate the work done by the weightlifter. The work done is equal to the force applied multiplied by the distance moved.

The force applied is equal to the weight of the object, which is the mass multiplied by the acceleration due to gravity (9.8 m/s^2):

Force = Mass × Acceleration due to gravity
Force = 150 kg × 9.8 m/s^2

Next, we need to calculate the distance moved by the weightlifter. The height raised is given as 2 meters.

Now, we can calculate the work done:

Work = Force × Distance
Work = (150 kg × 9.8 m/s^2) × 2 m

Finally, we can calculate the power output using the given time:

Power = Work / Time
Power = [(150 kg × 9.8 m/s^2) × 2 m] / 1.5 s

By plugging in the values and performing the calculations, you will find the power output during the lift.

To find the power output of the weightlifter during the lift, we need to use the formula:

Power = Work / Time

First, let's find the work done by the weightlifter. Work is calculated using the formula:

Work = Force * Distance

Here, the force is equal to the weight being lifted, which is the mass multiplied by the acceleration due to gravity (9.8 m/s^2). So, the force is:

Force = Mass * Acceleration due to gravity

Given that the weight being lifted is 150 kg, we can calculate the force:

Force = 150 kg * 9.8 m/s^2

Next, we need to find the distance. The distance moved by the weightlifter is the height raised, which is given as 2 m.

Now that we have the force and the distance, we can calculate the work:

Work = Force * Distance

Finally, we can substitute the work and the given time (1.5 s) into the power equation to find the power output:

Power = Work / Time

With all these values, we can now calculate the power output.
