A special train is traveling down a long, straight track with a constant acceleration of 9m/s^2 in the forward direction. The train is located on Mars where the acceleration due to gravity is

Question

9 m/s^2.

If a passenger drops a ball and measures the acceleration of the ball, the acceleration will be
a_{total} = ____________ m/s^2

Answer 1

in the horizontal direction the ball has no acceleration once let go (no horizontal force)
so now it is 9 m/s^2 down

by the way, g on Mars about the same as earth ? FALSE
