When a man walks towards east the frictional force is applied in?
When a man walks towards the east, the frictional force is applied in the opposite direction of his motion, which is towards the west. This frictional force acts to oppose the motion of the man and helps to keep him from slipping.
Why a man lifting a box to be placed on a table is work?
In physics, work is performed when a force is applied to an object and causes it to move in the direction of the force. In this scenario, the man lifting the box is applying a force to move the box upwards against the force of gravity. The work done is equal to the force applied multiplied by the distance the box is lifted.
When a man pushes on a wall with a force of 50 N . what are the size and the direction of the force that the wall exerts on the man?
The wall exerts a force of 50 N back on the man, as per Newton's third law of motion. This force is equal in magnitude but opposite in direction to the force applied by the man.
How many pounds of force is applied to man 250 lbs falling 3 feet?
The main force would be the force of gravity, which is 250 pounds in this case.
When a man is walking - work done or not?
No work is done on the man himself as he walks, as work is defined as force applied over a distance in the direction of the force. The man is the one exerting a force to overcome friction against the ground, causing him to move forward. Therefore, work is done by the man to move himself.
When a man applies some force on a wall of mass 200 kg but the acceleration in the wall is zero find the force applied by the man with the formula F equals ma?
You can't find the force from that data. The TOTAL force must be zero if there is no acceleration - but any force provided by the man, pushing against the wall, is counteracted by the Earth pushing back.
How much force is required to dislocate a shoulder?
"To dislocate a shoulder you need alot and i mean alot of force" Actually no. The amount of force required to dislocate a shoulder depends on the position the shoulder is and the direction force is applied. Ex: An arm stretched straight forward(90 degrees, straight) is the most difficult to dislocate if the force is applied to the front of the shoulder. If I remember correctly it takes a force of 84ish N(18.89 pounds of force) to the middle deltoid to dislocate a shoulder in that position(an average man can punch at between 60-90 foot lbs I think, I read it somewhere and can't find it again) Again it all depends on the position of the shoulder and the position of the force applied to the shoulder.
A man pushes a lawn mower with a force of 200 N across 50 meters of his lawn. How much work did the man perform?
The work done by the man is calculated by multiplying the force applied by the distance moved in the direction of the force. In this case, the work done is 10,000 Joules (200 N * 50 m).
A 150 pound man is standing on a lever one foot from the fulcrum. How much effort must be used to lift the man if the effort is applied six feet from the fulcrum?
6 x 150 pounds. 900 pounds of force would have to be applied.
If a man pushes a van against a force of 300N for a distance of 10m in a 5 seconds?
The work done by the man is calculated as the product of the force applied, the distance moved in the direction of the force, and the cosine of the angle between the force and the direction of movement. The work done can be calculated using the formula: work = force * distance * cos(theta), where the force is 300N, the distance is 10m, and the cosine of the angle is typically 1 when the force and displacement are in the same direction. Thus, the work done by the man would be 300N * 10m * 1 = 3000 Joules.
A man pushes a large box across a rough wooden floor. The box moves with constant velocity. What can be said about the forces acting on the box?
There is no unbalanced force acting on the box.
Can a woman squeeze a man's ribs with her legs and break them?
It is unlikely for a woman to break a man's ribs simply by squeezing them with her legs. However, if excessive force is applied or if there are underlying medical conditions, it may be possible to cause injury. It is important to always prioritize safety and consent in any physical interaction.
