Question

A. If you have two objects with different masses hit each other the force between them will be the same or different when they hit. Explain

B. If you have two vectors and you want to get the sum of these vectors. How many ways you could do that, explain your answer in more details, don't just give a numbe

Answer 1

(A) The force between them will be equal in magnitude but opposite in direction as per Newton's third law.

(B) We can add vector geometrically and algebraically In the geometric process, the tail of any second vector will be kept on the head of the first vector. Then joining the head of second with the tail of first vector will give the resultant vector. The first and second vector can be chosen arbitrarily as the order does not matter.

In the algebraic process, vectors must be represented the Cartesian form. Now the similar component will be added separately, For example, consider two vectors in cartesian form.

then their sum will be
