The correct option is (A): \(\frac{9}{16}\)
\(\frac{P^2}{2m}=K\)
\(\Rightarrow \frac{K_1}{K_2}=(\frac{m_2}{m_1})=\frac{16}{9}=(\frac{m_2}{m_1})\)
\(\Rightarrow (\frac{m_1}{m_2})=\frac{9}{16}\)
A body of mass 1000 kg is moving horizontally with a velocity of 6 m/s. If 200 kg extra mass is added, the final velocity (in m/s) is:
Kinetic energy of an object is the measure of the work it does as a result of its motion. Kinetic energy is the type of energy that an object or particle has as a result of its movement. When an object is subjected to a net force, it accelerates and gains kinetic energy as a result. Kinetic energy is a property of a moving object or particle defined by both its mass and its velocity. Any combination of motions is possible, including translation (moving along a route from one spot to another), rotation around an axis, vibration, and any combination of motions.
