{C - V}.
Answer:
10 N
Explanation:
While many people would like to simply add the forces from each end to get a total force, this is fundamentally incorrect.
MIGHT BE TOTALLY WRONG
This is false. There were many times in history when people discovered something that they didn't even know was possible or didn't even plan to discover it. Knowing tradeoffs doesn't mean that something won't surprise you or that all will go according to plan.
Acceleration: is the change in velocity divided by the time it takes for the change to occur. . Acceleration is the change in verity divided by the time it takes to make the change, Acceleration has direction.
Answer:
Now when it will reach at point B then its normal force is just equal to ZERO
Explanation:
Since we need to cross both the loops so least speed at the bottom must be
also by energy conservation this is gained by initial potential energy
so we will have
now we have
here we have
R = 7.5 m
so we have
Now when it will reach at point B then its normal force is just equal to ZERO
now when it reach point C then the speed will be
![mgh - mg(2R_c) = \frac{1}{2]mv_c^2](https://tex.z-dn.net/?f=mgh%20-%20mg%282R_c%29%20%3D%20%5Cfrac%7B1%7D%7B2%5Dmv_c%5E2)
now normal force at point C is given as
