AI Thread Summary
The discussion revolves around calculating the acceleration of a 35 kg block of cement under a net force of 150 N using Newton's second law of motion. The initial calculation of acceleration was incorrectly stated as a = m/f instead of the correct formula a = f/m, leading to an initial answer of 4.2 m/s². Upon re-evaluation and proper rounding, the correct acceleration was determined to be 4.3 m/s². Participants emphasized the importance of accurate calculations and rounding. The thread highlights common pitfalls in physics homework and the value of peer assistance.

Homework Statement


What is the acceleration of a 35 kg block of cement when pulled sideways with a net force of 150 N?


Homework Equations



what i did was f=ma
a=m/f

and just plugged the numbers in

The Attempt at a Solution



i got 4.2 but when i entered it into the assignment it told me i was wrong.
can someone explain to me where i went wrong?

You mean, I hope, a = f/m.

Probably just a round off error. Redo the calculation more accurately, then round off to two digits.
 
i feel so silly
the answer was 4.3
i just needed to round up =P
oh the irony,

thanks so much for helping!

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 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
