vf=vi+at;a=g;vf=0
0=339.81t;t=339.81.53s

Explanation:

  • GIVEN: a projectile shot at angle, θ=π3;vi=6ms
    find the time require maximum height, i.e. zero velocity at tyhe top.
  • DEFINITION AND PRINCIPLES: here what tou need a kinematic equation that use initial velocity, final velocity and acceleration (gravity in this case)
    vfy=viy+ayt;a=g;vfy=0;viy=6sin(π3)=33;
    0=339.81t;t=339.81.53s
