A projectile is thrown upward at an angle $\displaystyle 60^{\circ}$ with the horizontal. The speed of the projectile is $\displaystyle 20 \mathrm{~m} / \mathrm{s}$ when its direction of motion is $\displaystyle 45^{\circ}$ with the horizontal. The initial speed of the projectile is $\displaystyle \_\_\_\_$ m/s.
