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)=3√3;
0=3√3−9.81t;t=3√39.81≈.53s
