Two masses each with mass 0.10 kg are moving with velocities 3 m/s alo

1.	Two masses each with mass 0.10 kg are moving with velocities 3 m/s along x axis and 5 m/s along y-axis respectively. After an elastic collision one of the mass moves with a velocity 4i + 4j. The energy of other mass after collision is x/10 then x is.
Answer» KE_i = KE_f 1/2m x 25 + 1/2 x m x 9 = 1/2m x 32 + 1/2mv² 34 = 32 + v² KE = 1/2 x 0.1 x 2 = 0.1 j = 1/10 x = 1

Two masses each with mass 0.10 kg are moving with velocities 3 m/s along x axis and 5 m/s along y-axis respectively. After an elastic collision one of the mass moves with a velocity 4i + 4j. The energy of other mass after collision is x/10 then x is.

Answer»

KE_i = KE_f

1/2m x 25 + 1/2 x m x 9 = 1/2m x 32 + 1/2mv²

34 = 32 + v²

KE = 1/2 x 0.1 x 2 = 0.1 j = 1/10

x = 1
