Home » Mechanics » Motion in a Plane » Question

A particle moves in a circle of radius 5 cm with constant speed and time period 0.2 πs. The acceleration of the particle is

1. 15 m/s²
2. 25 m/s²
3. 36 m/s²
4. 5 m/s²

Correct Option: D

Centripetal acceleration a_c = ω²r

=		2π		²	r
		T

=		2π		²	× 5 × 10^-2 = 5 m / s²
		0.2π
