0Question : student stands on a scale in an elevator at rest on the 64th floor of a building. The scale reads 834?
As the elevator approaches the 74th floor, the scale reading drops as low as 755 N. What is the acceleration of the elevator?

Answer by bolexisist
first find the mass of the person, when the elevator is at rest the only acceleration is that of gravity
F = mg
834 = 9.81 m
m = 85 kg
next, when the elevator is moving the accel of the elevator is pointing up, while the accel of gravity is pointing down, so the total accel is the difference between the two
F = m(g – a)
F = mg – ma
755 = 834 – 85a
a = 0.93 m/s^2

A student stands on a bathroom scale in an elevator at rest on the 64th floor of a building. The scale reads 839 N.
(a) As the elevator moves up, the scale reading increases to 949 N, then decreases back to 839 N. Find the acceleration of the elevator.
(b) As the elevator approaches the 74th floor, the scale reading drops to 782 N. What is the acceleration of the elevator?

Answer by kuiperbelt2003
we will apply newton’s second law; the forces acting on the scale are the normal force (up), weight (down) and these combine to produce an ma term, in other words
N-mg = ma
the scale reading measures the normal force.
if the reading at rest is 839N, the student’s mass is
839N/9.8m/s/s = 85.6kg
a) N-mg = ma
if N=949, we have
949 = mg+ma
949=85.6g+85.6a
a=1.28m/s/s in the positive direction
b) if N=782N, then
782=mg+ma
782-85.6g=85.6a
a=-0.66m/s/s (slowing down as it approaches the floor)

Compare this exactly and choose the one that suits your needs best. This work real well if you are staying somewhere temporarily and do not want to tear the wall with a bracket mount. Check out the following tips for choosing TV stands that work for you:
1st Look at the price. Something that costs £ 500 more robust than something that costs £ 50. Think about getting a good deal? Take a look at the material its made of. Will look a little cheaper in general Sun A good idea is to save you money to buy models or discontinued models. These are not cheap, has not needed any longer. TV is bought in this way, usually last a long time.
2nd Decorative elements. What color is it? Will your decor? What material? You would not want a wooden TV stand, if all your furniture is made of black leather or metal and glass. These considerations are usually the first things you see how they are the most visible with the naked eye.

Another disadvantage is that many times installation is required, costing countless wasted minutes and frustration. If you buy at the store that contains a multiple delivery and you will not have wasted the time, frustration and anxiety by themselves together.
4th Size does matter. Before you go on a search for TV stands, do not forget to measure the space you have. Do you have the speakers? How will they be stored and where? Make sure the tripod you deep enough to hold all your components and DVDs, when you go to your media to your next entertainment centers are.
5th Do your research. If you are the houses of others, ask where they bought their TV stands, if one is to admire really. Also research your supplier. When buying online, about their opinions and shipping costs. If you look at a store near you a thorough understanding of policy and its return are guaranteed.
6th Skip the warranty. Unlike expensive electronics, TV is rarely going to stop working for you. Guarantees are less important when you go to a sumo wrestler or massive Partier concerned about your new state to break. . Guarantees on furniture are usually a waste of time. Check for an upgrade program, although, as to do so could, if you are starting small.
