Maharashtra Board Class 12 Textbook Solutions | CIRCULARMOTION

 Somehow, an ant is stuck to the rim of a bicycle wheel of diameter 1 m. While the bicycle is on a central stand, the wheel is set into rotation and it attains the frequency of 2 rev/s in 10 seconds, with uniform angular acceleration. Calculate (i) Number of revolutions completed by the ant in these 10 seconds. (ii) Time taken by it for first complete revolution and the last complete revolution. [Ans:10 rev., ti.„, = Vi. 6 s, tki, = 0.5132 s ] 

 




 

Coefficient of static friction between a coin and a gramophone disc is 0.5. Radius of the disc is 8 cm. Initially the centre of the coin is 'V cm away from the centre of the disc. At what minimum frequency will it start slipping from there? By what factor will the answer change if the coin is almost at the rim? (use g = m/s2) 1 2 [Ans: 2.5 rev/s, n2 = -1.1,] 

 


Part of a racing track is to be designed for a curvature of 72 m. We are not recommending the vehicles to drive faster than 216 kmph. With what angle should the road be tilted? By what height will its outer edge be, with respect to the inner edge if the track is 10 m wide? [Ans: 0 =tan1(5) = 78.69°, h = 9.8 m1 

 

The road in the question 14 above is constructed as per the requirements. The coefficient of static friction between the tyres of a vehicle on this road is 0.8, will there be any lower speed limit? By how much can the upper speed limit exceed in this case? [Ans: .L4 88 kmph , no upper limit as the road is banked for 0 > 45"

pt1. the only way centripetal / tangential makes sense is if you take vector approach. Otherwise there is lot of hand waving. 
 
pt 2. when Normal force is zero - person has flown away.

centripetal force is a fancy way of saying NET FORCE @2:50. v^2/r is never part of FBD.
 
 
when Normal force is zero - person has flown away.
