Question

If a projectile is shot at an angle of `(7pi)/12` and at a velocity of `18 m/s`, when will it reach its maximum height?

Answer 1

`t=1.78 " "s`

Explanation:

`v_i:"Initial velocity ; "v_i=18" "m/s`

`alpha:"Projectile angle ; "alpha=(7 pi)/12 " "sin alpha=0.97`

`g=9.81 " "N/(kg)`

`t=(v_i*sin alpha)/g`

`t=(18*0.97)/(9.81)`

`t=1.78 " "s`
