A ball is kicked at an angle of 30 degrees into the air. At the highest point, the ball has zero vertical velocity and zero horizontal acceleration.

• True

• False

What equation should be used to compute for the horizontal initial velocity of an object projected at an angle?

• v_ix = v_i sin θ

• v_ix = v_i cos θ

• v_iy = v_i sin θ
