What is the power expended when a barbell is lifted 2.2m in 2 seconds?
Wiki User
∙ 11y ago
The power during the lift is (weight of the barbell in Newtons)/4.4 watts.
Note:
Power is not "expended". Energy is. Power is the rate at which energy is expended.

How do you find the power of an object that lifted a 50 kg crate in 5 seconds?
First you calculate the energy required to lift the object: potential energy = mgh (mass x gravity x height). Note that your problem statement doesn't mention the height - you need that, too. Energy will be in Joule. Then you divide the energy by the time, to get power (in Watt).
What is the power of 50 joules in 5 seconds?
Power = energy/time = 50/5 = 10 watts
During a storm an apartment building lost power for 2.6 hours. For how many seconds was the power out?
9060 sec. (Apex)
How long is one quadrillion seconds?
A quadrillion is 10 to the 15th power. This is illustrated even more when you convert that to years (in seconds, not days). 1 year = 365 days. 365 days is 31,536,000 seconds (60 seconds * 60 minutes * 24 days * 365 days). 10 to the 15th power divided by 31,536,000 seconds = 31709791.983764585 years. Rounded up that is 31,709,792 years.

What power is expended of 100 N box is lifted the distance 2 meters in 1.0 Sec?
The formula for power is: amount of work / time interval 200 J / 1 sec. The amount of power expended: 200 Watts
What is the power expended by a person who carries a 50N moving box 3m in 3 seconds?
Power = force x displacement / time taken So power = 50 x 3 / 3 = 50 W Power expended = 50 W
What is the power expended if a boy pulls a sled up a hill is 425 J in 10.5 seconds?
247 W

Measures weight lifted regardless of time?
measure of weight lifted regardless of time
How do you Calculate the power output of a Person that bench presses 150 pounds 30 times in 10 seconds and moves the barbell a distance of 24 inches during each press?
Power is defined as work over time. Thus, we must first calculate the work involved in moving the barbell. W = Fd = 150 lbs * 2 ft = 300 ft-lbs per rep The work expended over the entire work out is thus 30 * 300 ft-lbs = 9000 ft-lbs. Since P = W/t, the power output is P = 9000 ft-lbs/10s = 900 ft-lbs/sec, which is about 1222 watts.
Who expended the power of royal court?

What is the definition of electric power?
There is no such thing as 'electric power'. Power is simply a rate: the rate at which energy is expended.
What is an example of the physics definition of power?
Power is the rate of work done or rate of energy generated or expended
