Question #3ea48

Answer 1

`794.2"m"`

Explanation:

The expression for range is :

`d=(vcostheta)/(g)(vsintheta+sqrt((vsintheta)^(2)+2gy_0))`

`y_0` is the height of launch which, in this case, is `114"m"`.

`:.d=(90xx0.92)/(9.8)(90xx0.39+sqrt((90xx0.39)^(2)+(2xx9.8xx114)))`

`d=8.449(35.1+sqrt(1236+2234.4))`

`d=794.2"m"`
