Skateboarder is attempting to make a circular arc of radius r= 15 m in a parking lot. The total mass of the skateboard and skateboarder is m= 99kg. The coefficient of static friction between the surface of the parking lot in the wheels on the skateboard is us = 0.58. (A) what is the maximum speed, in meters per second, he can travel through the arc without slipping? (b) he speeds up very slightly and begins to slide. The coefficient of kinetic friction is up=0.18. What is the new magnitude of his radio acceleration in m/s^2? 
A pulley (in the form of a uniform disk) with
mass Mp and radius Rp is attached to the
ceiling in a uniform gravitational field g and
rotates with no friction about its pivot. Mass
M2 is larger than mass mı, and they are
connected by a massless inextensible cord.
T1, T2, and Ts are magnitudes of the tensions.

NEED SOLUTION
A car traveling on a flat (unbanked), circular track accelerates uniformly from rest with a tangential acceleration of 1.75 m/s. The car makes it one quarter of the way around the circle before it skids
off the track. From these data, determine the coefficient of static friction between the car and track.
0.56
You appear to have forgotten that the static force of friction is also responsible for the tangential acceleration of the car.
