The mud flies off the tyre of a fast moving car in the direction
Correct answer: B. tangent to the moving tyre
- A. parallel to the moving tyre
- B. tangent to the moving tyre
- C. anti parallel to the moving tyre
- D. none of these
Explanation
The mud flies off the tyre of a fast moving car in the tangential direction.The reason for this is that the mud is subjected to a centrifugal force as the tyre rotates. This centrifugal force acts outwards, perpendicular to the axis of rotation. When the mud loses contact with the tyre, it continues to move in the tangential direction, due to inertia.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
