Answer:
Explanation:
Since the surface is frictionless, momentum will be conserved. If the bullet of mass 
has an initial velocity 
and a final velocity 
and the block of mass 
has an initial velocity 
and a final velocity 
then the initial and final momentum of the system will be:
Since momentum is conserved, 
, which means:
We know that the block is brought to rest by the collision, which means 
and leaves us with:
which is the same as:
Considering the direction the bullet moves initially as the positive one, and writing in S.I., this gives us:
So kinetic energy of the bullet as it emerges from the block will be:
Answer:
Walking while alternating knee lifts with each step.
Standing up and sitting down from a chair without using your hands.
Standing with your weight on one leg and raising the other leg to the side or behind you.
Explanation:
Those are the ones that I could best come up with.
The simplest answer is that gravity is the field created by a mass distribution in the spacetime around it; gravitational force is the force exterted by the field on a test mass in the field.
