Question

Weight on Different Planets An astronaut weighs 700 N on Earth. The table below shows the acceleration due to gravity on different planets. Planet | Acceleration due to gravity (m/s2) Earth | 9.8 Mars | 3.7 Jupiter | 24.8 Moon | 1.6

A ball is dropped from height h. The velocity attained by the ball just before reaching the ground is

ASSERTION: When a body is dropped or thrown horizontally from the same height it would reach the ground at the same time REASON: Horizontal velocity has no effect on the vertical motion

Two balls of different masses are thrown vertically upward with the same initial speed. Which one will rise to a greater height?
