Passaga : Asmau block of mass Mmones on frictionless Surface of an Inclined plane, as shown in figure. The angl of gncline suddenly changs prom 46 to 30 at point B. The block is dniti ally at rest at A. Aume that colisions betuuen block amd gncline oe totally nelatie 30 30 3V3M 1Q: The speed of the block at point B immediately aftr 9t strikes the second Sndene is 29: The Speed of block at point e immediatily efore st leane the Second Inchine is 3Q: Abau Strikes a horizontal foor at au normal to floor. The Coefficient of restitution betueen the bale and the kloor is e= 2. The proction of its Kinetic augle B=45 with the energy lost in Colision is.
