Find the mass of a body which has 5J of kinetic energy while moving at a speed of 2m/s (AS_(1))

In a collinear collision a particle with an intial speed v_(0) strike a stationary particle of the same mass. If the final total kinetic energy is 50 % greater than the original kinetic energy the magnitude of the relative velocity between the two particles after collision is .

Statement I: If a sphere of mass m moving with speed u undergoes a perfectly elastic head-on collision with another sphere of heavier mass M at rest ( M gt m ), then direction of velocity of sphere of mass m is reversed due to collision (no external force acts on system of two spheres). Statement II: During a collision of spheres of unequal masses, the heavier mass exerts more force on the lighter mass in comparison to the force which lighter mass exerts on the heavier one,

Nucleophilic aliphatic substitution reaction is mainly of two types: S_(N)1 and S_(N)2 . The S_(N)1 mechanism is a two step process. Reaction velocity of S_(N)1 reaction depends only on the concentration of the substrate. Since product formation takes place by the formation of carbocation, optically active substrate gives (+) and (-) forms of the product. In most of the cases the product usually consits of 5-20% inverted product and 80-95% racemised species. The more stable the carbocation, the greater is the proportion of racemisation. In solvolysis reaction, the more nucleophilic the solvent, the greater is the proportion of inversion. For the gives reaction, Which substrate will give maximum racemisation?

In an inelastic collision of two bodies, the quantities which do not change after the collision are the total kinetic energy/total linear momentum/total energy of the system of two bodies.

A plank P is placed on a solid cylinder S , which rolls on a horizontal surface. The two are of equal mass. There is no slipping at any of the surfaces in contact. The ratio of kinetic energy of P to the kinetic energy of S is:
