SATHEE: Kinematics Question 337

Kinematics Question 337

Question: The distance time graph of a particle at time makes angles $45^{\circ}$ with the time axis. After one second, it makes angle $60^{\circ}$ with the time axis.

What is the acceleration of the particle?

Options:

A) $\sqrt{3} - 1$

B) $\sqrt{3} + 1$

C) $\sqrt{3}$

D) 1

Show Answer

Answer:

Correct Answer: A

Solution:

Velocity at time t is $t a n 45^{\circ} = 1$ .

Velocity at time $(t = 1)$ is $t a n 60^{\circ} = \sqrt{3}$ .

acceleration is change in velocity in one second = $\sqrt{3} - 1.$
