Which of the following statements are true about power? Include all that apply.
Power is a time-based quantity.
Power refers to how fast work is done upon an object.
Powerful people or powerful machines are simply people or machines which always do a lot of work.
A force is exerted on an object to move it at a constant speed. The power delivered by this force is the magnitude of the force multiplied by the speed of the object.
The standard metric unit of power is the Watt.
If person A and person B do the same job but person B does it faster, then person A does more work but person B has more power.
The Newton•meter is a unit of power.
A 60-kg boy runs up a 2.0 meter staircase in 1.5 seconds. His power is approximately 80 Watt.
A 300-Newton force is applied to a skier to drag her up a ski hill at a constant speed of 1.5 m/s. The power delivered by the toe rope is 450 Watts
A person lifted a bag of groceries 2.89 m from the floor onto a counter top using a constant force of 55.0 Newtons. If the force was applied for 6.0 seconds, how much power was generated by the individual, to the nearest tenth of a watt?
A person used 60 W of power to carry a 55 N box up a 5 m ladder. How long did it take him to do this?
