The centripetal acceleration of a body moving with velocity 2 ms-1 in a circle of radius 0.3 m is:
Correct answer: B. 13.3 ms-2
- A. 0.6 ms-2
- B. 13.3 ms-2
- C. 0.15 ms-2
- D. 6.6 ms-2
Explanation
In this question, the centripetal acceleration of a body moving in a circle can be calculated using the formula: a = v2 / r, where v is the velocity and r is the radius of the circle. Plugging in the given values (velocity = 2 ms-1, radius = 0.3 m) into the formula, we get a = (22) / 0.3 = 4 / 0.3 = 13.3 ms-2. This is the correct answer. Option A, C, and D are incorrect because they do not follow the correct calculation method or have errors in the calculations.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
