SATHEE: Kinematics Question 423

Kinematics Question 423

Question: A particle is moving with velocity 5 m/s towards east and it’s velocity changes to 5 m/s north in 10 seconds. Find the average acceleration in 10 seconds.

Options:

A) $\sqrt{2} N - W$

B) $\frac{1}{\sqrt{2}} N - W$

C) $\frac{1}{\sqrt{2}} N - E$

D) $\sqrt{2} N - E$

Show Answer

Answer:

Correct Answer: B

Solution:

[b] $\vec{a} = \frac{{\vec{V}}_{f} - {\vec{V}}_{i}}{Δ_{t}}$ $\vec{a} = \frac{5 \hat{j} - 5 \hat{i}}{10}$ $| \vec{a} | = \frac{5 \sqrt{2}}{10} = \frac{1}{\sqrt{2}} m / s^{2}$ Direction North West
