# Applied physics

A golfer strikes a ball from a tee of negligible height. $$4.5$$ seconds later, the ball lands in a bunker $$225$$ meters away. At what initial speed, in $$m/s$$, was the ball hit?

Details:

• $$g=10 m/s^2$$

• The ground is perfectly level throughout.

• Ignore wind and air resistance.
