What is the mass of an elevator moving upwards with an acceleration of 2 meters per second, which experiences a tension of 6000N by the elevator cable. Please explain. Thanks!

Question

anonymous · Answer

Use formula $$\Sigma F=ma$$
rearrange the formula since you need to find the mass not the force.
so it should look like this
$$m=\Sigma F \div a$$
Then you just plug in the numbers in your calculator :D
The answer should be 3000kg

anonymous · Answer

there are two forces

anonymous · Answer

F-mg=ma
F= (a+g)m
m=F/(a+g)
m=6000/(2+10)=500kg
