An object is fired upwards from horizontal ground. The object has an initial velocity of 20 m s⁻¹ at an angle of 45° to the horizontal. Air resistance is negligible. Which statement describes the speed of the object after it is fired until immediately before it reaches the ground again?

1. AIts speed decreases to a value greater than zero, then increases to 20 m s⁻¹.
2. BIts speed decreases to a value greater than zero, then increases to a value greater than 20 m s⁻¹.
3. CIts speed decreases to zero, then increases to 20 m s⁻¹.
4. DIts speed decreases to zero, then increases to a value less than 20 m s⁻¹.
