Two identical stones are simultaneously thrown with the same initial speed from the roof of a building. One stone is thrown at an angle of 60 degrees above the horizontal, while the other is thrown horizontally. How will the speed of the stones compare at the instant just before each stone hits the ground? Explain in words and/or equations using concepts from chapters 7-9. (Spts)
Imagine standing on a skateboard on a horizontal surface and trying to jump forward as far as you can. How would the distance you are capable of jumping compare to if you were not on the skateboard? Explain in words and/or equations using concepts from chapters 7-9. (Spts)
