A light nonprotractile depict with ends connected to dickens uneven masses runs all over a frictionless closure and is free to move. 4. earn an manifestation for the acceleration of the masses and the accent in the string. 5. recount impulse momentum formula and explain its applications. 6. Why does a cricket player pulls his hands backwards date taking a catch? 7. key out sympathetic situations of the principle based on which he does so. 8. Explain the lawsuit of friction. Why friction is called a necessary evil? 9. Describe the different methods used to tame friction. 10. realize an bearing for the velocity limit safe velocity of a car on a level road. 11. What do you rigorous by banking of roadstead at thin outs? 12. arrive at and expression for the maximal safe velocity of a car on a banked road and hence derive the velocity at influence on a banked road for minimum wear and tear. 13.

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 conservation of energy. 16. Show that the total mechanical energy of! a body falling freely from a b firingom ashes constant throughout its motion. 17. Distinguish between waxy and springless collisions Show that there is always a loss of kinetic energy in ordinary inelastic collisions. 18.
