With same braking power you will be stopping faster on the original weight therefore the answer to fill the blank is increase. The stopping distance will increase as there'll be higher energy to dissipate than lighter cars applied with the braking force similar with that of the lighter car. Also the skid and drag will add to the distance as well as the inertia of the moving heavier vehicle would be greater as well.
Answer:
(a) 
(b) 
Explanation:
According to the law of conservation of momentum:
Initially, the girl and the plank are at rest. So, relative to the ice, we have:
(a) The velocity of the girl relative to the ice is:
Here, 
is the velocity of the girl relative to the plank and 
is the velocity of the plank relative to the ice.
Replacing (1) in (2):
(b) According to (2), the velocity of the plank relative to the surface of ice is:
The negative sing indicates that the plank is moving to the left.
