A controlled experiment is best described as a safe, in depth, and insightful display that helps you understand the purpose of the experiment better
Answer: I would say the object with the Lower velocity because Lighter with Higher velocity makes it heavy, velocity is how heavy something is so the lighter it is the less difficult it will be to catch.
Answer:
The correct option is;
d) F, because the net force is equal to the mutual contact force between the blocks
Explanation:
The given information are
The mass of block A = m
The velocity of block A = +v
The mass of block B = 2·m
The velocity of block B = -v
Given that the two blocks collide, we have;
Initial total momentum = m × v + 2·m×(-v) = m·(v - 2·v) = -m·v
Final total momentum = m × v₁ + 2·m×v₂ = m·(v₁ + 2·v₂)
From the law of conservation of linear momentum, we have;
m·(v₁ + 2·v₂) = -m·v
v₁ + 2·v₂ = -v
Therefore, the resultant velocity of the two blocks is -v, and the direction of the block A is reversed and the resultant inertia is equivalent to the inertia of block A
Therefore;
The force exerted on block B = The force exerted on block A = The rate of change of momentum experienced by the two blocks = The mutual contact force experienced between the blocks.
