The time taken isCentripetal force on a particle of mass m moving with speed v on a circle of radius r isCentrifugal force in a rotating frame is best described as aA car of mass 800 kg takes a turn of radius 40 m at 20 m/s on a level road. The minimum coefficient of static The relation between linear velocity v, angular velocity ω and radius r in circular motion isMoment of inertia of a thin uniform rod of mass M and length L about an axis through its centre perpendicular A wheel of moment of inertia 2 kg·m² is accelerated from rest to 60 rad/s in 10 s. The torque applied isA solid sphere and a hollow sphere of equal mass and radius roll without slipping with the same kinetic energy
