A crewman stands on a bathroom scale. In calm waters, the scale reads 183 lb . During storm, crewmen find a max reading of 225 lb and a minimum of 140 lb. Max acceleration upward/downward?

Answer 1

Upward: 225 - 183 = (183/g)a; a = 42g/183 = 2.25 m/s²

Downward: 140 - 183 = (183/g)a; a = - 43g/183 = -2.31 m/s²
