A particle starting from the origin (0, 0) moves in a straight line in the (x, y) plane. Its coordinates at a later time are (√(3), 3). The path of the particle makes with the x-axis an angle of (a) 45o (b) 60o (c) 0o (d) 30o.

Answer: (b). Slope of the straight path: tan θ = y/x = (3)/(√3) = √3 So the answer is (b) 60°.

Motion in a Plane (2-D Kinematics)

A particle starting from the origin (0, 0) moves in a straight line in the (x, y) plane. Its coordinates at a later time are $\left(\sqrt{3}, 3\right)$ . The path of the particle makes with the x-axis an angle of

Show answer and solution

Answer: (b)

Slope of the straight path: $\tan\theta = \frac{y}{x} = \frac{3}{\sqrt3} = \sqrt3$
So the answer is (b) $60^\circ$ .
