Is it 2/0.5?
I am not sure.
are you asking 2 or 0.5?

Is it 2 metre/second na?
It's one of the option
which one? please do say the options.
(a) 1N (b) 2N (c) 4N (d) 0.5 N
I think 2 * 0.5 = 1.
Can you explain it?
What I think is the conveyor belt is initially at rest. Gravel mass is 0.5 kg. Now given velocity is 2 m / s. So just multiplied using the force formula.
It is, but you need a reason behind it :D
I request others to check and criticize me if I am wrong.
force=momentum*time so momentum is given for unit time (1 second) determine it
So even my answer is correct I believe.
the force is nevertheless 0.5N no matter how u speed up
Momentum is mass*velocity
But How?
Abdul, What is the correct option given in the key?
Key was not given
Oooooooooooooooo
sry i dint read the question properly so yes first find momentum and then force
This was given in FIITJEE
I could know that. U can even find such questions in BMA workbook.
In 8th?
Yeah. Its actually 9th portion. Still u can try.
Write the net force as: \[\ F_{net}= F - F_{thrust} \] it is -F_thurst because the mass in increasing The net force is zero because the system is not increasing or decreasing its velocity, that is the velocity is constant. Now, \[\ F_{thrust}=v\frac{dm}{dt}\] I think it is fairly easy to solve it now :D.
Yeah. so my answer is correct.
What is dm/dt?
change in mass per unit time or how much mass is added per second.
Even I will know the use of "d" in formulae in 11th grade. Can anyone explain it in detail?
d is a symbol for a differential. It represents an infitesimal change of some quantity (you will get to that in calculus). It's like \[\ \Delta \] but infinitely small.
So, its a very tough concept. What about Calculus? I just know 2 words - Integration and Differentiation.
Yes that's what you do in Calculus :D. If you are impatient to learn about it I would recommend "Calculus" by Gilbert Strang Link: http://ocw.mit.edu/ans7870/resources/Strang/Edited/Calculus/Calculus.pdf
