How much work would a child do while pulling a wagon a distance of with a force?

Therefore, the work done by a child to pull wagon a distance of 4.3 m is 94.6J .

How do you find the acceleration of a wagon?

Your acceleration is found by: a = (change in speed) / (time) = 5 m/s divided by 10 seconds = 0.5 m/s2 So the net force = (100 kg) x (0.5 m/s2) = 50 N!

How do you calculate the work of friction?

The work done by friction is the force of friction times the distance traveled times the cosine of the angle between the friction force and displacement; hence, this gives us a way of finding the distance traveled after the person stops pushing.

How do you find net force with mass and angle?

Add 180 degrees to 49 degrees to get 229 degrees. The acceleration is in the same direction as the net force. to find the magnitude of the net force, giving you 102 N. Use the magnitude of the force and the mass to find the magnitude of the acceleration: a = F/m = (102 N)/(100 kg) = 1.0 m/s2.

Is work done if you pull a child in a wagon quizlet?

Is work done if you pull a child in a wagon? Yes, the force applied is parallel to the direction of motion.

How is the acceleration related to the mass of wagon?

When the mass of the wagon is doubled, the acceleration is half the original acceleration. This is because mass and acceleration are inversely proportional. When the force is doubled, the acceleration is doubled.

How do you calculate mass and acceleration?

It states that the rate of change of velocity of an object is directly proportional to the force applied and takes place in the direction of the force. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.

How do you calculate total work?

Summary

1. Work can be calculated with the equation: Work = Force × Distance.
2. The SI unit for work is the joule (J), or Newton • meter (N • m).
3. The equation for work can be rearranged to find force or distance if the other variables are known.

How do u find net force?

When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = Fa + Fg + Ff + FN.

Is work done if you pull a child in a wagon?

How much force does it take to pull a wagon?

A child pulls a wagon 3.0 m using a force of 55 N at an angle 35 degrees above horizontal. The force of friction on the wagon is 12 N. What is the net work done on the wagon? The total work done on the wagon is 99 J. It is best to calculate the work done by each force on the wagon and add them together.

What is the total work done on the wagon?

The total work done on the wagon is 99 J. It is best to calculate the work done by each force on the wagon and add them together. The equation we must use is where θ is the angle between the direction of the force and the direction of the displacement. Note the direction in the last case.

How do you calculate force from mass and acceleration?

Force Equation. Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.
