A cyclist turns around a curve at 15 miles/hour. If he turns at double the speed, the tendency to overturn is
Correct answer: A. Quadrupled
- A. Quadrupled
- B. Halved
- C. Unchanged
- D. Doubled
Explanation
F = mv^2/r As F is directly proportional to v^2 And F is tendency to overturn in a circular motion. Therefore, on doubling velocity, tendency to overturn in a circular motion becomes quadrupled.

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.
