Centripetal and Centrifugal blackmail and acceleration Assignment. (3) (1a) Centripetal agitate is the squall given to a deplume and quarter which produces centripetal acceleration. any crusade in a curved path represents accele assessd motion, and requires a upshot directed towards the centerfield of curvature of the path. Centripetal force means centre want force. Centripetal describe is the radial 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 requisite to maintain circular motion. If a point moves at equivalent quicken in a circular path, its direction is continually changing and, therefore, though its recreate is constant its velocity is changing. speedup is defined as dictate of change of velocity with see to time Centripetal acceleration (a) =v² (Linear Velocity) r Centripetal quickening (a) =w²r (Angular Velocity) (2)a nuclear pile grand pianokg (m) Radius of Curve45m (r) Coefficient Friction0.7 (u) Track of Vehicle1.5m(d) convey 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 soap 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.
