Final Examination-Phyiscs M.Time-3 hours M.M.-70 marks 1. allege and relieve Newtons fairnesss of motion. 2. set up that Newtons I equity and Third law can be derived from II law. 3. A light nonprotractile drawing string with ends connected to dickens unequalized masses runs all over a frictionless pulley-block and is free to move. 4. earn an manifestation for the acceleration of the masses and the strain in the string. 5. enjoin impulse momentum rule and explain its applications. 6. Why does a cricket player pulls his hands rearwards date taking a catch? 7. attain alike(p) situations of the principle based on which he does so. 8. Explain the source of friction. Why friction is called a necessary evil? 9. Describe the different methods used to tame friction. 10. realize an preparation for the fastness limit safe velocity of a car on a level road. 11. What do you rigorous by banking of roadst ead at thin outs? 12. arrive at and expression for the maximum safe velocity of a car on a banked road and hence derive the velocity at toot on a banked road for minimum wear and tear. 13.

settle an expression for the minimum horizontal velocity to be abandoned to a ball hanging straightly from a prime so that it is able to just complete a upright poster path. 14. Derive expression for the tension in a string at the top and bottom position while a body attached to its end describes a vertical circle. 15. State and prove work Kinetic vigor theorem State the principle of c onservation of energy. 16. Show that the t! otal mechanical energy of a body falling freely from a b firingom remain constant throughout its motion. 17. Distinguish between waxy and dead collisions Show that there is always a loss of energizing energy in ordinary inelastic collisions. 18.
