A 1000kg car is turning around a corner at 10ms-1 as the radius of circle is 10m. Find the centripetal force:
Correct answer: B. 1 x 10^4N
- A. 2 x 10^3N
- B. 1 x 10^4N
- C. .2 x 10^4N
- D. 0.5 x 10^4N
Explanation
Option B is correct.Given data: m=1000kg , v=10ms-1, r=10mFind out:Fc=?Solution:We know that:Fc=mv2/r = 1000(10)2/10 =1 x 104N

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.
