Question

The velocity of a projectile at the initial point A is $(2\hat{i}+3\hat{j})m/s$. Its velocity at point B is

• A. $2\hat{i}+3\hat{j}$
• B. $-2\hat{i}+3\hat{j}$
• C. $-2\hat{i}+3\hat{j}$
• D. $2\hat{i}-3\hat{j}$

Answer 1

The correct option is D $2\hat{i}-3\hat{j}$

H ­ component remains the same and V – component will be reversed.
