Calculating Force Needed to Pull Sled with 210kg Load

In summary, the force needed to pull a sled with a 210kg load can be calculated using the formula F=ma, where F is the force, m is the mass of the sled and load, and a is the acceleration. Several factors can affect this force, such as the mass of the load, the surface being pulled on, and the coefficient of friction. The surface can greatly impact the force, with a smooth surface requiring less force compared to a rough surface. The coefficient of friction can be determined experimentally and other factors like air resistance and incline should also be considered when calculating the force needed to pull the sled.

Homework Statement


Sled dog to pull on a snowy sleigh horizontal road, the mass of its load is 210 kg. Snow and sleigh runners movement between the friction coefficient is 0.095. Dogs sleigh force exerted by the horizontal. acceleration of 0.13 m/s2? Gravitational acceleration is 9.81 m/s2.

Homework Equations


How much force as the dogs pull the sled

The Attempt at a Solution


Newton second law and by projection:
F-Ff=m*a
F=m*a+Ff
F=210*0.13+0.095*210*9.81
F= 223.0095 N

Related to Calculating Force Needed to Pull Sled with 210kg Load

1. How do you calculate the force needed to pull a sled with a 210kg load?

The force needed to pull a sled with a 210kg load can be calculated using the formula F=ma, where F is the force, m is the mass of the sled and load, and a is the acceleration. In this case, the acceleration would be the force of friction acting against the sled.

2. What factors affect the force needed to pull a sled with a 210kg load?

The force needed to pull a sled with a 210kg load can be affected by several factors, including the mass of the load, the surface the sled is being pulled on, and the coefficient of friction between the sled and the surface.

3. How does the surface affect the force needed to pull a sled with a 210kg load?

The surface the sled is being pulled on can greatly affect the force needed to pull it. For example, a smooth, slippery surface will require less force compared to a rough, uneven surface with a higher coefficient of friction.

4. How can the coefficient of friction be determined for calculating the force needed to pull a sled with a 210kg load?

The coefficient of friction can be determined experimentally by measuring the force needed to move the sled on different surfaces and then using the formula F=μN, where μ is the coefficient of friction and N is the normal force acting on the sled.

5. What other factors should be considered when calculating the force needed to pull a sled with a 210kg load?

In addition to the factors mentioned above, other factors that should be considered when calculating the force needed to pull a sled with a 210kg load include any additional forces acting on the sled, such as air resistance or the incline of the surface the sled is being pulled on. These factors can also affect the amount of force needed to pull the sled.
