How Much Force Is Needed for a 450g Object to Accelerate at 8cm/s²?

AI Thread Summary
To calculate the net force required for a 450g object to accelerate at 8cm/s², the mass must first be converted to kilograms, resulting in 0.45kg. The acceleration should also be converted to meters, yielding 0.08m/s². The correct formula to use is F = m × a, where F is force, m is mass, and a is acceleration. Multiplying 0.45kg by 0.08m/s² gives a net force of 0.036N. This calculation clarifies the confusion regarding unit conversions and the application of the formula.

' a mass of 450 grams is given an acceleration of 8cm/s/s. Calculate the net force required.


so confused, the only question i couldn't get was this one.

hi pdot! :wink:

show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:
 


i got stuck because the units were not right . i converted grams into kilograms = .45kg and centimetres into metres = .08m . .45kg x .08m = .036N (Newtons)
 
ah! :smile:
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

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 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
