how much work is required to pull a sled if you use 60j of work in 5 seconds
Had this same problem on my homework, was confused, this helped. Thanks
To determine the amount of work required to pull a sled, you can use the formula:
Work = Force × Distance × cos(θ)
Where:
- Work is the amount of work done (in joules)
- Force is the applied force (in newtons)
- Distance is the displacement (in meters)
- θ (theta) is the angle between the force and the displacement
In this case, you have the amount of work (60 joules) and the time (5 seconds). However, we will need additional information to calculate the work accurately.
If we assume that the force applied to the sled is constant, and we know the time taken (5 seconds), we can calculate the average power using the formula:
Average Power = Work / Time
Substituting the known values:
Average Power = 60 J / 5 s = 12 watts
Therefore, the average power exerted to pull the sled is 12 watts. However, we still need more information to calculate the work accurately.
