Question

Loss of kinetic energy due to the direct impact of two bodies depends on mass of those two bodies and

• A. Difference between initial and final velocities
• B. initial velocity of the two bodies
• C. final velocity of the two bodies
• D. Product of initial velocities

Answer 1

Answer:

B. initial velocity of the two bodies

Loss of kinetic energy due to the direct impact of two bodies depends on mass of those two bodies and initial velocity of the two bodies colliding along the line of impact. $ΔE=\frac {m_1 m_2}{2(m_1+m_2)} (\nu_1-\nu_2)^2(1-e^2)$ where ν1​ and ν2 are initial velocities e is the coefficient of restitution​
