Question

A projectile is shot from the ground at a velocity of `93 m/s` at an angle of `pi/3`. How long will it take for the projectile to land?

Answer 1

`t_e=16,42 " s"`

Explanation:

`"elapsed time for the projectile can be calculated using"`
`"the formula "t_e=(2*v_i*sin alpha)/g`

`v_i:"initial velocity"`
`alpha:"projectile angle"`
`g:9,81" "(N)/(kg)`

`t_e=(2*93*sin(pi/3))/(9,81)`

`t_e=16,42 " s"`
