Question

38.
A 2 kg body and a 3 kg body have equal
momentum. If the kinetic energy of 3 kg
body is 10 J, the KE of 2 kg body will be​

Answer 1

Answer:

15 J

Explanation:

MOMENTUM = ROOT UNDER 2MK

MIS THE MASS AND K IS THE KINETIC ENERGY

MOMENTUM OF 3 KG BODY IS ,

2MK= 2*3*10 KG *METRE /SECOND

MOMENTUM = 60 KG * METRE / SECOND

ATP,

MOMENTUM OF 2 KG BODY IS 60,

SO ,

2*2*KINETIC ENERGY= 60 KINETIC ENERGY= 15 J
