Answer:
W=1055N
Explanation:
In order to solve this problem, we must first do a drawing of the situation so we can visualize theh problem better. (See attached picture)
In this problem, we will ignore the board's weight. As we can see in the free body diagram of the board, there are only three forces acting on the system and we can say the system is in vertical equilibrium, so from this we can say that:

so we can do the sum now:

when solving for the Weight W, we get:

and now we can substitute the given data, so we get:
W=410N+645N
W=1055N
The stone will take 2.89 seconds to hit the water.
The time required by the stone to hit the water is calculated by the second equaiton of motion
s=ut+
gt^2
41=0×t+
×9.81×t²
t=2.89 seconds
Answer:
Explanation:
As 5 sheets represent the distance from earth to sun and the Oort cloud is 50000 times farther away,
5(50000) = 250 000 sheets
I would think that it would be a spring scale based on the readings that I have done on Hooke's law. Hooke's law states that the force exerted on a spring is directly proportional to the distance it moves as a result of the force. The spring scale is used to measure the weight of objects. I hope this answered your question.
Peace out!
