Q: A particle of mass m moves rectilinearly due to force F = F_{0} – bx, where F_{0} and b are positive constants, x is the distance from the point, where the particle was initially at rest. Find the distance covered by the particle till the moment it came stand still.

(a) F_{0}/b

(b) 2F_{0}/b

(c) 3F_{0}/b

(d) F_{0}/2b

Ans: (b)
