An object of mass m is thrown vertically upward from the surface of earth, where the acceleration due to gravity is ga. the initial speed is va, and the object reaches a maximum height of ya. if a similar object is thrown upward with initial speed vb = 9va from the surface of saturn\'s moon titan, its maximum height is yb. the acceleration due to gravity on titan is gb. express the ratio of yb to ya in terms of ga and gb.

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
