The work done on the couch is given by the formula: Work = Force x Distance. In this case, the work done is 400N x 4m = 1600 J (joules).

What is the net force 400N left 200N right?

The net force is 200N to the left (400N - 200N = 200N).


What is the mechanical advantage of a jack that is able to lift a 5000N car with 400N of effort?

The mechanical advantage of the jack is calculated by dividing the load force (5000N) by the effort force (400N). In this case, the mechanical advantage of the jack is 12.5, meaning that for every 1 unit of effort applied, the jack is able to lift 12.5 units of load.


If the downward force on an object equals 800 N and the area over whch the force is excerted is 2 meter squared what is the pressure exerted?

800N/2m^2 = 400N/m^2


If someone pulls using a force of 400N in a tug of war and his opponent does the same with 400N of force what is the resulting tension?

The formula for tension is T = mg +/- ma. Thie tension on the rope is still only 400 N, regardless if one person is pulling or two people are pulling.


Find the net force including its direction what 175N to the left 234N to the right 75N to the right 225N to the left 45N to the right.?

To find the net force, we need to consider the forces in the left and right direction separately. The total force to the left is 175N + 225N = 400N (to the left). The total force to the right is 234N + 75N + 45N = 354N (to the right). Therefore, the net force is 400N - 354N = 46N to the left.

What is the net force on a 1000-n barrel falling in air with an air brag of 400n?

The net force on the barrel is 600 N downward (1000 N - 400 N). This net force causes the barrel to accelerate downward as per Newton's second law, F = ma, where F is the net force, m is the mass, and a is the acceleration.


A boy of mass 40kg runs up a flight of 50 steps each of 10cm high in 5 sec find the power developed by the boy?

The total vertical height the boy climbs is 50 steps * 10cm = 500cm = 5m. The work done by the boy is the force (mg) * distance (5m) = 40kg * 9.8 m/s^2 * 5m = 1960 J. Power is work done divided by time, so the power developed by the boy is 1960 J / 5 sec = 392 watts.


An object with a mass of 9 kg experiences a force of 16.2 N What is the acceleration of the object?

A newton is a kg *m/ s^2. Acceleration is in m/s^2. Thus divide the force in Newtons by kilograms and you will get an acceleration value.In this case: 20 N / 100 kg = 0.2 m/ s^2


A different staging that weighs 300 N supports two painters one 250 N and the other 300 N The reading in the left scale is 400 N What is the readin in the right hand scale?

Total downward force = 300 + 250 + 300 = 850N Total reaction (upward) force must be 850N = scale left (400N) + scale right. So scale right must be 450N.


If a weightlifter presses 400n weight 0.5m over his head in 2 seconds what is the power of the weightlifter?

Power is calculated using the formula: Power = Work / Time. The work done in lifting the weight can be calculated as Work = Force × Distance, which is 400 N × 0.5 m = 200 Joules. Therefore, the power of the weightlifter is 200 Joules / 2 seconds = 100 Watts.


If phil weighs 600 N and stands on two bathroom scales and one scale reads twice as much as the other what are the scales reading?

One scale is reading 200N and the other is reading 400N.
