an astronaut on the planet zircon tosses a rock horizonally with a speed of 6.95 m/s. the rock falls through a vertical distance of 1.40 m and lands a horizontal distance of 8.75 m from the astronuat. what is the acceleration of gravity on zircon?

Answer 1

The horizontal speed is 6.95 m/s
So, if it falls for t seconds, it will travel 6.95t meters.

8.75 = 6.95t
t = 1.259s

Now, s = 1/2 at^2
1.40 = 1/2 a * 1.585
a = 1.766 m/s^2

Answer 2

Planet Zircon or Planet Zirconia. Earth is Planet Zircon?
Perhaps. I never understood the message...
