In summary, a child uses a broom stick at a 60 degree angle to push a 2.0kg bucket of water across a floor. The broom stick exerts a force of 100N, while the bucket encounters a frictional force of 10N over a distance of 5.0m. Using g=9.8m/s/s and assuming negligible air resistance, the work done can be calculated by: A) the horizontal component of the 100N force, B) the frictional force, and C) the resultant horizontal force. This can be done by using the formula W=F\cdot d, where W is work, F is force, and d is distance. It is helpful to draw

A Child uses a broom stick to push a 2.0kg bucket of water across a floor. The Broom Stick is held at an angle of 60 degrees to the horizontal and exerts a force of 100N on the bucket. The bucket is initially at rest and encounters a constant frictional force of 10N while moving a distance of 5.0m. Assume the g is 9.8m/s/s, and that the effects of air resistance are negligible.

For the 5.om distance, calculate the work done by:
A) the horizontal component of the 100N Force

B) The frictional Force

C) The Resultant horizontal Force

Have you tried drawing a free body diagram of the forces involved and finding the net horizontal force?

Use [itex]W=F\cdot d[/itex] to calculate the work.

1. What is force and how is it measured?

Force is a physical quantity that is defined as any influence that can cause an object to undergo a change in motion. It is measured in units of newtons (N) using a device called a force meter or spring scale.

2. What are the different types of forces?

There are four fundamental forces in nature: gravity, electromagnetism, strong nuclear force, and weak nuclear force. Other types of forces include friction, tension, normal force, and applied force.

3. How does Newton's laws of motion relate to force?

Newton's laws of motion describe the relationship between force, mass, and motion. The first law states that an object will remain at rest or in motion with constant velocity unless acted upon by a net force. The second law states that the acceleration of an object is directly proportional to the net force and inversely proportional to its mass. The third law states that for every action, there is an equal and opposite reaction.

4. How do we calculate force?

Force is calculated using the equation F=ma, where F represents force, m represents mass, and a represents acceleration. Force can also be calculated using the formula F=mg, where g represents the acceleration due to gravity (9.8 m/s² on Earth).

5. How does force affect motion?

According to Newton's second law, the greater the force acting on an object, the greater its acceleration will be. This means that an object with a larger force acting on it will experience a greater change in motion than an object with a smaller force. Force can also change the direction of an object's motion, as seen in circular motion or when a net force is not in the same direction as an object's velocity.
