Question

Ball A is dropped from the top of a building. At the same instant ball B is thrown vertically upwards from the ground. When the balls collide, they are moving in opposite directions and the speed of A(u) is twice the speed of B. The relative velocity of the balls just before collision and relative acceleration between them is (only their magnitudes)(A) zero and zero(B) 'g' and zero(C) '3u//2' and '2g' (D) '3u//2' and '3u//2'​

Answer 1

Answer:

Ball `A` is dropped from the top of a building. At the same instant ball `B` is thrown vertically upwards from the ground. When the balls collide, they are moving in opposite direction and the speed of `A` is twice the speed of `B`.
