Constant velocity means the netto force = 0, therefore F(gravity) = F(astronaut).
175N divided by 87,5kg = 2.00kg/N

To solve this problem we will apply the kinematic equations of linear motion and centripetal motion. For this purpose we will be guided by the definitions of centripetal acceleration to relate it to the tangential velocity. With these equations we will also relate the linear velocity for which we will find the points determined by the statement. Our values are given as


PART A )


Calculate the velocity of the motorcycle when the net acceleration of the motorcycle is 




Now calculate the angular velocity of the motorcycle



Calculate the angular acceleration of the motorcycle



Calculate the time needed by the motorcycle to reach an acceleration of




PART B) Calculate the velocity of the motorcycle when the net acceleration of the motorcycle is 




PART C)
Calculate the radial acceleration of the motorcycle when the velocity of the motorcycle is 



Calculate the net acceleration of the motorcycle when the velocity of the motorcycle is 



PART D) Calculate the maximum constant speed of the motorcycle when the maximum acceleration of the motorcycle is 




Answer:

Explanation:
From the Question we are told that:
Mass 
Coefficient of kinetic friction 
Generally the equation for Frictional force is mathematically given by



Generally the Newton's equation for Acceleration due to Friction force is mathematically given by



Therefore
