Power is defined as the rate at which the body is doing work:
Work is defined as displacement done by the force times that displacement:
We know that we need 62N to move the box, so when we apply this force along the path of 10m we have done:
of work.
Now we just divide that by 5s to get how much power is required:
Answer:
T = 243.80 N
Explanation:
In order to calculate the tension T in each of the cables, you take into account the Newton second law for the vertical component of the forces involved.
(1)
where you have used the fact that both cables have the same tension T, and they make the same angle with the horizontal.
W is the weigh of the loudspeaker and has the folowing values:
Next, you can calculate the angle θ by using the information about the length of the cables and the distance from the ceiling to the loudspeaker:
Finally, you solve the equation (1) for T, and then you replace the values of the other parameters:
The tension in each cable is 243.80N

Answer:
Purplemath
The first term in the binomial is "x2", the second term in "3", and the power n is 6, so, counting ... x12 + 18x10 + 135x8 + 540x6 + 1215x4 + 1458x2 + 729 ... So memorize the Theorem and get the easy points.
