can someone please help me with these: thanks a bunch:
1) The olympic diving tower is 10 meters high. The top platform is about three meters long.
A good runner could get into trouble by taking a running dive and overshooting the length of the diving pool.
Make a reasonable assumption about a good runner's maximum speed and estimate the minimum length for a "safe" diving pool.
2) A football is kicked at ground level in such a way that the horizontal component of its initial velocity is 7 m/s, while the vertical component is 10 m/s. When it returns to the ground the football will have a speed of about:
17 m/s.
7 m/s.
12 m/s.
It cannot be determined from the data.
