When you drive a car around a curve that is not banked, what force provides the centripetal acceleration? if the curve is banked, what additional force plays a role in providing the centripetal force?

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.

By what factor does the drag force on a car increase as it goes from 65 to 110 km/h?

When a person spins a bucket of water in a circle, the force acting on the bucket to keep the water inside is called
