The slope of a line on any distance-time graph represents the speed of the object.
Velocity only comes in when there is speed of the object in a particular direction.
Answer:
(a) 
(b) 
Explanation:
According to Newton's second law:
Recall that the frictional force is related jointly with the coefficient of friction and normal force 
. Replacing in the above equation, we get the coefficient of friction:
(a) The coefficient of static friction is related with the force required to set the block in motion:
(b) The coefficient of kinetic friction is related with the force required to keep the block moving with constant speed:
