1.	9. Two bodies A and B with masses 4 kg and16 kg, respectively, have the same kineticenergy. Calculate the ratio of velocity of A to B.
Answer» ANSWER:k=1/2mv^2 K.E1=k.e2 M1v1^2=m2v2^2 M1/m2=(v2/v1)^2 4/16=(v2/v1)^2 There for v1/v2=squareroot(4:1) V1/v2=2:1 Step-by-step EXPLANATION:

9. Two bodies A and B with masses 4 kg and16 kg, respectively, have the same kineticenergy. Calculate the ratio of velocity of A to B.

Answer»

ANSWER:k=1/2mv^2

K.E1=k.e2

M1v1^2=m2v2^2

M1/m2=(v2/v1)^2

4/16=(v2/v1)^2

There for v1/v2=squareroot(4:1)

V1/v2=2:1

Step-by-step EXPLANATION:
