Acceleration of an inclined plane?

AI Thread Summary
To achieve an acceleration of 0.5 m/s² on a 1.143-meter inclined plane without considering friction or weight, one can use the equation a = g * sin(theta), where g is 9.8 m/s². By rearranging this equation, the angle theta can be calculated to determine the necessary incline. The discussion emphasizes the importance of understanding the relationship between gravitational acceleration and the incline's angle. Trial and error may not be necessary if the correct calculations are applied. Proper use of the equation will provide the required angle for the desired acceleration.

If I have a ramp that is 1.143 meters long, and I need to make it incline at a certain angle and height to make sure the acceleration is .5 m/s^2, how would I go about doing that without taking friction into account and without weighing anything?

How might you find the component of the acceleration due to gravity parallel to the incline?
 
i am so lost on this, not sure if it's just trial and error or if I can use some type of equation
 
do i do a=gsin(theta) where g is 9.8

Exactly.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
