Question

A projectile is shot from the ground at a velocity of `1 m/s` at an angle of `(5pi)/12`. How long will it take for the projectile to land?

Answer 1

`t_e=0,197" s"`

Explanation:

`"given data:"`
`"initial velocity :"v_i=1" "m/s " (red vector)"`

`"angle :"alpha=(5pi)/12`

`sin alpha~=0,966`

`"solution:"`
`"formula for elapsed time : " t_e=(2*v_i*sin alpha)/g`

`t_e=(2*1*0,966)/(9,81)`

`t_e=0,197" s"`
