Question

A ball initially at rest, breaks into two masses m1 and m2 that move with speed 11 and v2 respectively as shown. The ratio of the kinetic energy of the right mass to the left mass is:

• A. $\frac{m_1}{m_2}$
• B. $\frac{m_2}{m_1}$
• C. $\frac{m_1^2}{m_2^2}$
• D. $\frac{m_2^2}{m_1^2}$

Answer 1

Answer: (B)

$\frac{m_2}{m_1}$

Answer 2

The Correct answer is option is (B) : $\frac{m_2}{m_1}$
