Suppose that a ball is dropped from the upper observation deck of the \( \mathrm{CN} \) tower, \( 450 \mathrm{~m} \) above the ground. The position of the ball is described by \( s=4.9 t^{2} \). What is the average velocity of the ball in the interval between 5 seconds and 10 seconds? All answers below are in the units \( \mathrm{m} / \mathrm{s} \). 5 \( 4.9 \frac{100+25}{5} \) \( 4.9 \frac{100-25}{5} \) Using the same information as the previous problem. How fast is the ball moving at 5 seconds? All answers below are in the units \( \mathrm{m} / \mathrm{s} \). \( 4.9 \lim _{h \rightarrow 0} \frac{(5+h)^{2}+25}{h} \) 49 \( 4.9 \lim _{h \rightarrow 0} \frac{(5+h)^{2}-25}{h} \) 98
