$t_e=16,42 " s"$

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

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

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

$t_e=16,42 " s"$

A projectile is shot from the ground at a velocity of 93 m/s93 m/s at an angle of pi/3pi/3. How long will it take for the projectile to land?
