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