A body of mass 200kg per from circular motion ofradius 50cm at a constant sрееd of 240rpm findsits linear speed. |
| Answer» E here is your answerhope it helps you Given:Radius, R=0.5mAngular acceleration, α=2 rad/s 2 Time, t=2sAssumption:Acceleration asked is for a point on the rim.After 2 s, ANGULAR velocity is given by:ω=ω o +αtω=0+2×2ω=4 rad/sCentripetal Acceleration is given by, a c =ω 2 R=4 2 ×0.5=8 m/s 2 Tangential Acceleration is given by, a t =Rα=0.5×2=1 m/s 2 NET acceleration, a net = a c2 +a t2 a net = 8 2 +1 2 ≈8m/s 2 | |
