Answer:
a) 
b) 
c) 
Explanation:
From the question we are told that:
Initial angular velocity 
Initial Length 
Final angular velocity 
Final Length 
a)
Generally the rotation with the greater speed is

b)
Generally the equation for centripetal acceleration at 8.16 is mathematically given by



c)
At 6.35 rev/s


I believe the answer would be oxygeon deficit.
From the information provided, the velocity after 2 seconds is 11 m/s.
From the equations of motion;
v = u + at
Where;
v = final velocity
a = acceleration
t = time taken
The initial velocity of the bike was 7 m/s and its acceleration is 2 m/s2. This change occurred within a time of 2 seconds.
Hence;
v = 7 + 2(2)
v = 11 m/s
The velocity after 2 seconds is 11 m/s.
