Kinematics Question 399
Question: Two balls A and B of same mass are thrown from the top of the building. A thrown upward with velocity v and B, thrown down with velocity v, hen
Options:
A) velocity a is more than B at the ground
B) velocity of b is more than A at the ground
C) both A & B strike the ground with same velocity
D) None of these
Show Answer
Answer:
Correct Answer: C
Solution:
If a is the height of the building, then $ v _{A}^{2}\text{=}{{v}^{2}}\text{+2gh and v} _{B}^{2}={{( -v )}^{2}}+2gh $
Clearly $ v _{A}= v _{B} $
