Question

A cylindrical drum has a radius of 0.45 m and is initially at rest. It is then given an

angular acceleration of 0.40 rad s−2

. At time t = 8.0 s calculate (i) the angular speed of

the drum, (ii) the centripetal acceleration of a point on the rim of the drum, (iii) the

tangential acceleration at that point, and (iv) the resultant acceleration at that point.​

Answer 1

12is the drum ,the centipetal accelation
