you can ignore the horizontal speed of the marble (unless you want to find out far far it travels).
s = 1/2 at^2
1.5 = 1/2 * 9.8 t^2
t = 0.55 sec
Consider a marble moving on a horizontal track with a speed of 10 meters per second( ignore friction and air resistance). the marble leaves the track and falls through the air to the ground a vertical distance of 1.5 meters.
how long does it take to for the marble to hit the ground?
