a. What is the maximum speed that the car could drive in a horizontal circle of radius r = 11 m without “drifting”? That is, the car’s wheels roll without slipping in this part.
b. How fast could the car “drift” in a horizontal circle of radius 11 m? When “drifting”, all four wheels slip with respect to the road.
c. How fast could the car drive up the spiral (helical) ramp, at constant speed v, without “drifting?” Hint: The spiral motion of the car can be decomposed into motion in a horizontal circle at constant speed vh plus vertical motion at constant speed vy. The slope of 7.5◦ is always in the direction of motion of the car (and not perpendicular to this direction as for a banked curve).
d. How fast could the car drive up the spiral (helical) ramp, at constant speed v,when “drifting”

In the movie The Fast and the Furious: Tokyo Drift,a the bad guy “drifts” a Nissan 350Z at constant speed up a spiral ramp in a parking garage. The radius of the spiral is 11 m, and the slope of the spiral is 7.5◦. The coefficient of static friction between the tires and the road is µs =0.48, and the coefficient of kinetic friction is µk =0.42

It will take a few more days to finish my mechanics problem booklet.... Exclusively for JEE ADVANCED.
More than 120+ problems are there
Disclaimer: it's not for everyone 🌚
All the best keep grinding, as jee main is near and your patience too will be at the boundary
Just stay calm for another 2 months and ensure that your 1st attempt should give you enough motivation to fight for jee advanced....
