Match the following: ( array |l|l|l|l| & Column I & & Column II A. & Elastic collision & P. & e=0 B. & Inelastic collision & Q. & O initial K.E array )

Options

  1. AA-(P); B-(Q); C-(R); D-(S)
  2. BA-(R); B-(P); C-(Q); D-(S)
  3. CA-(S); B-(R); C-(Q); D-(P)
  4. DA-(R); B-(Q); C-(S); D-(P)

Correct answer

D. A-(R); B-(Q); C-(S); D-(P)

Step-by-step solution

(A) Elastic collision - By definition, perfectly elastic collision has coefficient of restitution (e=1 ). ((A) (R) ). (B) Inelastic collision - For inelastic collisions (not perfectly plastic), coefficient of restitution lies between (0 Initial K.E. ( (C) (S) ). (D) Plastic collision (perfectly inelastic) - In a perfectly plastic collision, bodies stick together, so (e=0 ). ( ( D ) ( P ) ).
