Physics Two Dimensional Motion Question 121
The velocity of a projectile at the initial point A is $ ( 2\widehat{i}+3\widehat{j} ) $ m/s. Its velocity (in m/s) at point B is
Options:
A) $ -2\widehat{i}+3\widehat{j} $ B)$ 2\widehat{i}-3\widehat{j} $ C) $ 2\widehat{i}+3\widehat{j} $ D) $ -2\widehat{i}-3\widehat{j} $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] At point B the direction of velocity component of the projectile along Y - axis reverses. Hence, $ {{\overrightarrow{V}} _{\text{B}}}=2\hat{i}-3\hat{j} $
