Then you can find the power by using P = W/t.In summary, the conversation discusses the calculation of power generated by a force on a 1100 kg object being pulled at a constant velocity of 5 m/s on a horizontal surface. The relevant equation, W = Fdcos37*, is mentioned and it is recommended to solve for d assuming the mass starts from rest. The power can then be found using the formula P = W/t. The need for free body diagrams is also mentioned.

A 1100 kg object is pulled across a horizontal surface at a constant velocity of 5 m/s. What is the power generated by this force? (Picture includes object being pulled at a 37 degree angle above the horizontal with a Force of 122 N)

Bangdeek27, welcome to PF!. Please read the forum rules and follow the format listed when you post. Homework helpers will not assist with any questions until you've shown your own effort on the problem. Remember, we help with homework, we don't do your homework. Please list what you believe are the relevant equations and show some attempt at a solution. Thanks.

Well I thought that power just = force x velocity, so (122)(5) = 610 watts. However I really don't think its that simple. I don't understand how to do any free body diagrams for this problem, though I feel they are needed.

Uhe formula for work: W = Fdcos37*, solve for d by assuming that the mass starts from rest.
 

1. What is power calculation?

Power calculation is the process of determining the amount of work done per unit time. It is a measure of how quickly energy is transferred or converted from one form to another.

2. How is power calculated for an object?

Power is calculated by multiplying the force applied to an object by its velocity. In other words, power (P) = force (F) x velocity (v).

3. What is the formula for power calculation?

The formula for power calculation is P = F x v, where P is power, F is force, and v is velocity.

4. How is power calculated for a 1100 kg object moving at 5 m/s?

To calculate power for a 1100 kg object moving at 5 m/s, you will need to know the force that is acting on the object. Once you have the force, you can multiply it by the velocity of the object to determine the power.

5. What are the units of power in this calculation?

The units of power in this calculation are watts (W). However, other units such as horsepower (hp) or joules per second (J/s) may also be used to measure power.
