Centripetal And Centrifugal Force

Centripetal and Centrifugal business leader and quickening Assignment. (3) (1a) Centripetal agitate is the roaring given to a resume and quarter which produces centripetal acceleration. any(prenominal) crusade in a curved path represents accele assessd motion, and requires a force directed towards the midsection of curvature of the path. Centripetal force means centre pursuance force. Centripetal military posture is the radiate force which acts ON a rotating mass and Centrifugal Force is the radial force which is exerted BY a rotating mass. (1b) Centripetal acceleration is the inwards acceleration infallible to maintain circular motion. If a point moves at render quicken in a circular path, its direction is continually changing and, therefore, though its amphetamine is constant its velocity is changing. quickening is defined as rank of change of velocity with evaluate to time Centripetal quickening (a) =v² (Linear Velocity) r Centripetal acceleration (a) =w²r (Angular Velocity) (2)a atomic pile g-forcekg (m) Radius of Curve45m (r) Coefficient Friction0.7 (u) Track of Vehicle1.5m(d) nub of Gravity0.68m(h) Acceleration (force of gravity)9.81 m/s²(g) Without skidding outwards, Centrifugal force = frictional resistance to skidding = m v² = u m g r slime stimulate v = ?u g r =? 0.7 x 9.81 x 45 =? 309.015 = 17.5788 m/s Convert to km/h= (17.5788m/s x 3.6) = 63.
