The velocity of a projectile at the initial point AA is (2i+3j)m/s(2 \mathbf{i}+3 \mathbf{j}) \mathrm{m} / \mathrm{s}. Its velocity (in m/s\mathrm{m} / \mathrm{s} ) at point BB is The velocity of a projectile at the initial point A is (2 i+3 j) m / s . Its velocity (in m / s ) at point B is

Options

  1. A−2i−3j-2 \mathbf{i}-3 \mathbf{j}
  2. B−2i+3j-2 \mathbf{i}+3 \mathbf{j}
  3. C2i−3j2 \mathbf{i}-3 \mathbf{j}
  4. D2i+3j2 \mathbf{i}+3 \mathbf{j}

Correct answer

C. 2i−3j2 \mathbf{i}-3 \mathbf{j}

Step-by-step solution

From the figure the XX-component remain unchanged, while the YY-component is reverse. Then, the velocity at point BB is (2i−3j)ms−1(2 \mathrm{i}-3 \mathrm{j}) \mathrm{ms}^{-1}.
