They need to touch each other. Equilibrum, is when two things touch that arent the same heat, once they touch, they are equal in temperature, so they need to touch. hope i helped :D
Answer:
maximum possible velocity = ![\sqrt{ugR}](https://tex.z-dn.net/?f=%5Csqrt%7BugR%7D)
Explanation:
centripetal acceleration when the car is going in the circle must be less than the maximum friction for the car to not slip.
centripetal acceleration ![\frac{mv^{2}}{r}](https://tex.z-dn.net/?f=%5Cfrac%7Bmv%5E%7B2%7D%7D%7Br%7D)
where v is the velocity of car and r is the radius of circle
maximum friction = umg
where u is the coefficient of static friction.
therefore![umg\geq \frac{mv^{2}}{R}](https://tex.z-dn.net/?f=umg%5Cgeq%20%5Cfrac%7Bmv%5E%7B2%7D%7D%7BR%7D)
therefore maximum possible velocity = ![\sqrt{ugR}](https://tex.z-dn.net/?f=%5Csqrt%7BugR%7D)
What is the longest the bolt can be and still be acceptable
Answer:9m
Explanation:
Ball starts from rest . Time taken = 6 seconds. Distance travelled by ball. ∴Distance travelled = 9 m
Hope it helps you
Good luck
