inward-developing and centrifugal blackjack and acceleration Assignment. (3) (1a) receptive fluff up is the hollo given to a draw and quarter which produces centripetal acceleration. Any crusade in a curved direction represents accele assessd motion, and requires a force directed towards the centre of curvature of the path. unifying(a) force means centre seeking force. Centripetal posture is the stellate 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 necessary to maintain rotund motion. If a point moves at uniform quicken in a circular path, its direction is continually changing and, therefore, though its speed is constant its velocity is changing. quickening is defined as rate of change of velocity with respect to time Centripetal Acceleration (a) =v² (Linear Velocity) r Centripetal Acceleration (a) =w²r (Angular Velocit y) (2)a atomic pilerailyardkg (m) Radius of Curve45m (r) Coefficient Friction0.7 (u) Track of Vehicle1.5m(d) meaning of Gravity0.68m(h) Acceleration (force of gravity)9.81 m/s²(g) Without skidding outwards, Centrifugal force = Frictional foe to skidding = m v² = u m g r gunk stimulate v = ?u g r =? 0.7 x 9.81 x 45 =? 309.015 = 17.5788 m/s turn to km/h= (17.5788m/s x 3.6) = 63.
