Assuming ideal projectile motion, calculate the range (to the nearest meter) of a projectile fired from the origin over horizontal ground at an initial speed of \( 500 \mathrm{~m} / \mathrm{sec} \) and a launch angle of 60 degrees. Note: Use g=9.8 meters per second squared Question 4 Assuming ideal projectile motion, find the initial speed of a football kicked at an angle of 45 degrees if it just barely cleared a 10 feet high crossbar of the goalpost that is 150 feet from the point of the kick. Note: Use g=32.174 feet per second squared Question 5 Find the length of the curve for \[ \vec{r}(t)=\left\langle 6 t^{3},-2 t^{3},-3 t^{3}\right\rangle \quad 1 \leq t \leq 2 \]
