Question

A projectile is shot from the ground at a velocity of `16 m/s` and at an angle of `(5pi)/6`. How long will it take for the projectile to land?

Answer 1

`t=1,63 s`

Explanation:

`v_i=16m/s" initial velocity"`
`alpha=(5pi)/6 " angle"`

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

`g=9,81 m/s^2`

`t=(2*v_i*sin alpha)/g`

`t=(2*16*0,5)/(9,81)`

`t=1,63 s`
