# At a certain instant, a  fly ball has velocity v(vector)=25i-4.9jx axis is horizontal, y axis is upward, v is in m/s.Has the ball passed its highest point?the answer is supposed to be NObut the y velocity is -ve so shouldn't the answer be YES?

he must have taken downward direction of y-axis as +ve and upward as -ve.

so the ball did not still pass the highest point.

As the y component of velocity has negative direction which indicates that body is moving downward that's why it has passed it's highest point! So the answer is yes!

yes, since it’s -4.9j it means that projectile has negative acceleration (to positive y axes) and because we know that acceleration constant is 9.8m/s we can assume that projectile passed it’s maximum height 0.5 seconds ago.
