Q1. A 3.55-kg object is thrown vertically upward from the surface of Mercury, where the acceleration due to gravity is g1 = 3.70 m/s2. The initial velocity is v1, and the object reaches a maximum height of y1. What is the maximum height, y2, if the object is thrown with a speed of v2 = 1.99v1 from the surface of Jupiter's moon Io? The acceleration due to gravity on Io is g2 = 1.79 m/s2. Give the reply as a multiple of y1.
