ANY time, no matter how short, will set the block in motion. The force can then
be taken away, because on a frictionless surface, NO force is required in order
to keep the block moving.
The work done is equal to the kinetic energy you want the block to have. That
can be as much or as little as you feel like giving it.

A person who is not wearing a seatbelt during a collision will be thrown forward because it maintains forward motion
Further explanation
In Newton's law, it is stated that if the resultant force acting on an object of magnitude is zero, it can be formulated :
then the object tends to defend itself from its state. So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called inertia
The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.
In objects with mass m that move translatively, the object will maintain its linear velocity
When we are in a vehicle that moves forward, then we will still maintain a state of forwarding motion. If our vehicle stops suddenly, then we keep moving forward so we will be pushed forward. From this point, the use of a safety belt serves to hold back our movements so that there are no fatal accidents or collisions.

The person not wearing the seat-belt during a collision may hit the dashboard of the car very hard and this injury might be fatal.
Explanation:
The inertia of a body is a property contained by the body by virtue of its mass. Higher the mass of a body, higher will be the inertia.
According to the Newton's first law of motion i.e. law of Inertia, a body continues to be in its state of rest or motion until and unless an external force acts on the body to change its state.
When a car is moving on a road, the car is in motion and the body of the person in the car is also in the motion along with the car. Now if the car faces any collision, the car will suddenly come to rest.
But the body of the person sitting in the car continues to be in motion as there is no external force acting on the body. If the person is not wearing the seat-belt, the body moves forward and the person may hit the dashboard very hard.
The seat-belt stops the person's body to move ahead and hit the dashboard. So, the seat-belt prevents the person from injury by stopping the body.
Thus, The person not wearing the seat-belt during a collision may hit the dashboard of the car very hard and this injury might be fatal.
