Question

Momentum of two masses m1 and m2 is same. If m1 >m2 and KE represents kinetic energy , then​

Answer 1

Answer:

KE with m1>=< KE with m2

Explanation:

As m1 is more so velocity should be less than other velocity.

Now if 1/2mv² if we will do then we can get three results as mass and velocity is not given.

Answer 2

Explanation:

momentum is same therefore

M1 V1 =M2 V2= P (LETS SAY )---------1

M1>M2 HENCE, V1<V2 (TO MAKE 1 TRUE)

1/2(M1 V1^2)=K.E 1 =1/2(M1.V1)V1

KE 1 = 1/2x p x V1

K.E2=1/2(M2.V2)V2

K.E 2= 1/2x p x V2

SINCE V1<V2

(P/2)x V1 < (P/2)x V2

K.E 1 < K.E 2
