Problem 68GP
(a) If the horizontal acceleration produced by an earthquake is a, and if an object is going to “hold its place” on the ground, show that the coefficient of static friction with the ground must be at least μs = a/g. (b) The famous Loma Prieta earthquake that stopped the 1989 World Series produced ground accelerations of up to 4.0 m/s2 in the San Francisco Bay Area. Would a chair have started to slide on a linoleum floor with coefficient of static friction 0.25?

ANSWER:
SOLUTION: Step 1 of 3 Any mass object thrown from earth surface after some time again it falls on the earth surface due gravitational full of earth and always which acts downwards. During the journey of the object one more force resist motion of the object and which acts on the body which is called drag force or air resistance
