A 2 kg particle slides in a horizontal circle of radius 5 m with a constant speed of 3 m/s on a rough surface. The only vertical forces on it are its weight and the normal reaction; nothing is known about the other horizontal forces. The coefficient of kinetic friction is 0.4 and m/s². Then:
Options:(select one or more)
Answer:
A, B
Solution:
N, so kinetic friction is N (A). It opposes the velocity and so lies along the tangent (B). C and D are false.
