Figure shown a man standing stationary with respect to a horizontal converyor belt that is accelerationg with `1m//s^(-2)` . What is the net force on the man?If the coefficient of ststic friction between the man's shoes and the belt is `0.2` upto what maximum acceleration of the belt can the man continue to be stationary relative to the belt? Mass of the man`= 65kg (g =9.8m//s^(2))`
