Question

ASAP PLZZ FINALS TOMR GIVE U ALOT OF POINTSS

Answer 1

B

Step-by-step explanation:

Let m be mass of the object and v be speed of object b.

Kinetic Energy of B = 1/2 mv^2

Kinetic Energy of A = 1/2 m(2v)^2

= 2 mv^2

= 4 (1/2 mv^2)

= 4 × Kinetic Energy of B

Hence Object A has four times the kinetic energy of object B (Ans B)
