<span>The importance of discovering gravitational
waves are; one, we can measure the activity between two bodies in orbit in the
universe, two, scientist can estimate the merging of two bodies in the universe
every 15 minutes by using LIGO and three, we can know the behavior of other
bodies that we did not know exist.</span>
Momentum is a vector quantity, and is always conserved. Whenever a collision occurs between two objects, the objects behave under the principle of conservation of momentum. Therefore, if an object moves in the direction opposite to its original direction after a collision, then this indicates that the momentum of the colliding object was greater than the object under consideration.
Answer:
Explanation:
As we know that backpack is kicked on the rough floor with speed "v"
So here as per force equation in vertical direction we know that
so normal force on the block is given as
now the magnitude of kinetic friction on the block is given as
now when bag is sliding on the floor then net deceleration of the block due to friction is given as
now we know that bag hits the opposite wall at L distance away in time t
so we have
