Consider speed of bicyclist 1 as V1=+8m/s and bicyclist 2 as V2=-2m/s  m=80kg 

Since momentum has opposite signs moving to right or left   

Therefore the combined momentum , P is given by :   

P=m*V1+m*V2 =80*(8-2)kg*m/s=+480 kg m/s

Answer:

B. decreases while his angular speed remains  unchanged.

Explanation:

His angular speed will always be the same as the wheel's angular speed, which remains constant as it's in uniform motion. As for linear speed, which is defined as the product of angular speed and distance r to the center of rotation, and his distance to center is decreasing, his linear speed must be decreasing as well.
