( Question 16 of 19 ) An object of mass m is thrown vertically upward from the surface of Venus, where the acceleration due to gravity is g5. The initial speed is ab, and the object reaches a maximum height of yb. If a similar object is thrown upward with initial speed 0,, = 70;, from the surface of Saturn's rnoon Titan, its maximum height is ya. The acceleration due to gravity on Titan is 3'\". Express the ratio of ya to y, in terms of 3;, and go. (0 Macmillan Lea rning A rocket is launched from rest with a time-dependent acceleration a(t) = (p - rt), where p = 19.00 m/s and r = 2.00 m/s3. Find the maximum velocity of the rocket. @ Macmillan Learning Umax m/s
