Question

According to the figure the following will

A) increases B) decreases C) stays the same
D) equal to E) greater than F) less than

Answer 1

1)As the angle θ decreases, the normal force of the ramp on the block _______ .
2)As the angle θ increases, the block's weight _______ .
3)If the block is moving up the ramp at decreasing speed, T is _______ the normal force of the ramp on the block.
4)If the block is moving down the ramp and θ = 30°, its speed initially _______ if T = Mg/2.
5)If the block is moving up the ramp at increasing speed, T is _______ the block's weight component

Answer 2

@ybarrap if you could assist me on this one it would be greatly appreciated

Answer 3

Do you know how to resolve the forces acting on the block?

Answer 4

@ybarrap If you mean turning the forces into components I do know how

Answer 5

What I mean is this. What are the normal forces for a given \(\theta\)? What are the frictional forces? If you know this last force, you'll know the tension in the string.

So for 1. What is the normal force? See if you can draw it.

Answer 6

Fn= mgsin(theata)

Answer 7

Right, so as \(\theta \) gets smaller, what happens to Fn?

Answer 8

it decreases
