Question

A projectile is shot from the ground at a velocity of `19 m/s` at an angle of `pi/3`. How long will it take for the projectile to land?

Answer 1

`t_e=3,35 " s"`

Explanation:

`"data:"`
`v_i=19 " m/s initial velocity"`
`alpha=pi/3" angle"`
`g=9,81 m/s^2`
`t_e=? " elapsed time"`

`t_e=(2*v_İ*sin alpha)/g`

`t_e=(2*19*0,866)/(9,81)`

`t_e=3,35 " s"`
