Question

If a projectile is shot at an angle of `(2pi)/3` and at a velocity of `26 m/s`, when will it reach its maximum height?

Answer 1

`t_m=2,29 " s"`

Explanation:

`"given data:"`
`"initial velocity :"v_i=26 m/s`
`"angle :"alpha=(2pi)/3`
`sin(2pi)/3=0,866`
`"elapsed time to reach its maximum height :"t_m=(v_i*sin alpha)/g`
`g=9,81 m/s^2`

`t_m=(26*0,866)/(9,81)`

`t_m=2,29 " s"`
