Explanation:
Given:
length of the stick,
position of holding the stick that acts as a hinge,
mass of the object,
position of hanging the mass on the meter stick,
new position of hanging the mass,
<u>Now the torque in the initial position:</u>
where:
acceleration due to gravity
Now when the mass is at the new position:
Explanation:
Concept: In collision between two isolated bodies momentum is always conserved.
Also, if the collision is elastic kinetic energies are also conserved
m1v1i + m2v2i = m1v1f + m2v2f.
and in elastic collision
Momentum is preserved in collisions between two objects. The initial moment not being zero, the final momentum is not zero. This means both object has to be in motion.
However, it may be possible for one of the objects to be at rest after the collision. For instance, if the masses of the two objects are same, then after a head-on elastic collision the object initially at rest is moving and the object initially moving is at rest.
