physics
A highway curve has a radius of 123 m. At what angle should the road be banked so that a car traveling at 26.5 m/s has no tendency to skid sideways on the road? [Hint: No tendency to skid means the frictional force is zero.] I can't get this one right either please someone...

physics
A car drives around a curve with radius 390 m at a speed of 32 m/s. The road is not banked. The mass of the car is 1200 kg. (a) What is the frictional force on the car? N c) Explain I really don't know how to solve this could someone please help me out on this. Thank you.

Physics
A cylindrical 7.00-kg reel with a radius of 0.60 m and a frictionless axle, starts from rest and speeds up uniformly as a 3.00-kg bucket falls into a well, making a light rope unwind from the reel (Fig. P8.36). The bucket starts from rest and falls for 5.00s. (a) What is the l...
