Derive an expression for minimum speed required by a vehicle driven in horizontal circles of a well of Death without loosing contact.

Derive the expression for maximum safe speed with which vehicle should move along a curved horizontal road.

Derive an expression for most safe speed of a vehicle on a curved banked road ignoring friction.

Derive an expression for most safe speed of a vehicle moving on a curved banked road ignoring friction?

The safety speed of a vehicle on a curve horizontal road is

Derive an expression for upper limit on the speed of a vehicle at the top of a convex bridge?

Using the energy conservation, derive the expression for the minimum speeds at different locations along a vertical circular motion controlled by gravity. Also prove that the difference between the extreme tensions (or normal forces) depends only upon the weight of the object.

The safe speed of a vehicle on a horizontal curve road is independent is

Derive an expression for difference in tensions at highest and lowest point for a particle performing vertical circular motion.

During a stunt, a cyclist (considered to be a particle) is undertaking horizontal circles inside a cylindrical well of radius 6.05 m. If the necessary friction coefficient is 0.5, how much minimum speed should the stunt artist maintain? Mass of the artist is 50 kg. If she/he increases the speed by 20%, how much will the force of friction be?
