Explanation:

The speed of the javelin has two components, the x-component and the y-component. The x-component will remain constant, but the y-component will be affected by the gravitational acceleration. In order for the angle to be reduced to 16°, the y-component divided by the x-component should be equal to tan(16°):

$v_o = 23 m/s\\v_{ox} = 23m/s*cos(34°) = 19.06m/s\\v_{oy} =23*sin(34°) = 12.86 m/s$

$\frac{v_{1y}}{v_{1x}} = tan(16°) \\v_{1y} = tan(16°)*v_{1x} = tan(16°)*19.06 m/s = 5.47 m/s$

And, knowing that:

$a = \frac{v_f - v_o}{t} \\t = \frac{v_f - v_o}{a} = \frac{v_{1y} - v_{oy}}{g} = \frac{5.47m/s - 12.86m/s}{-9.81m/s^2} = 0.75s$
