Question

A projectile is shot from the ground at a velocity of `36 m/s` and at an angle of `(5pi)/6`. How long will it take for the projectile to land?

Answer 1

`t_e~=3,67" s"`

Explanation:

`""given data:"`

`v_i=36" "m/s" "alpha=(5pi)/6" "t_e=?`
`v_i:"initial velocity"`
`alpha:"projectile angle"`
`t_e:"elapsed time for the projectile"`

`"formula : "t_e=(2*v_i*sin alpha)/g`

`sin((5pi)/6)=0,5`

`t_e=(2*36*0,5)/(9,81)`

`t_e~=3,67" s"`
