A car of mass 1000kg travelling at 40ms-1 rounds a curve of radius 100m. What is the Fc?
Correct answer: C. 1.6 x 10^4N
- A. 100 N
- B. 1.6 x 10^6 N
- C. 1.6 x 10^4N
- D. 8 x 10^4N
Explanation
Option C is correct.Given data:m=1000kg, v=40ms-1, r=100mFind out: Fc=?Solution:According to the centripetal force formulaFc=mv2/r=1000(40)2/100=1.6×104NOptions A, B, and D are incorrect because they do not correctly calculate the centripetal force using the given data and formula. Option C provides the accurate calculation and solution for the centripetal force in this scenario.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
