Question

A projectile is shot at an angle of `(5pi)/12` and a velocity of `7 m/s`. How far away will the projectile land?

Answer 1

`x_"maximum"~=2,50" m`

Explanation:

`x_"maximum"=v_x*t_e`
`v_x: "the x component of velocity"`
`t_e:"elapsed time"`
`t_e=(2*v_i*sin alpha)/g" "t_e=(2*7*sin((5pi)/12))/(9,81)`
`t_e=1,38 s`
`v_x=v_i*cos((5pi)/12)" "v_x=7*cos((5pi)/12)" "v_x=1,81`
`x_"maximum"=1,81*1,38`
`x_"maximum"~=2,50" m`
