In preparation for my upcoming first exam I was doing all of the suggested problems throughout the chapters. Everything was fine until this problem:
An astronaut on the planet Zircon tosses a rock horizontally with a speed of 6.95m/s. The rock falls through a vertical distance of 1.4m and lands a horizontal distance of 8.75m from the astronaut. What is the acceleration of gravity on Zircon?
Distance=speed x time
Speed=distance/time
8.75m/6.95m/s=1.26s
1.4m/1.26s=1.11m/s
Now, I thought this was correct but according to the back of the book the answer is 1.77m/s which would be 1.4*1.26. Am I misunderstanding something?
