Answer
The glider's acceleration would decrease to zero when the mass holder strikes the ground. This is because there would be no resultant force acting on the glider once the connection is broken.
Step 2
The resultant force on it would decrease to zero.

Answer
Simultaneously, the resultant force acting on the glider would also decrease to zero as it no longer has the mass to pull against, resulting in a lack of net force and thus an acceleration of zero.
