FFD$2$ Haw high will the arrow be $7$ seconds after being shot upward at $50\frac{m}{s}?$

Since it has a speed of $20\frac{m}{s},$ the average velocity is $\frac{50+20}{2}\frac{m}{s}$ and the height $=\frac{{35}^N}{?}=245$ meters

Since the height is half of initial velocity $*$time$,$ the height is $175$ meters

Since the initial velocity was $50\frac{m}{s},$ the height is $350$ meters

Since it is falling back down at $-20\frac{m}{s},$ the average velocity is $\frac{50-20}{2}=15\frac{m}{s}$ and height $={15}^{**}7=105$ meters
