Hi guys,

Please see attached image - it's the part highlighted yellow that I'm stuck on.

Here is what I got for linear velocity and angular velocity. (requested by mod)

Thanks!

Dia=0.8m .. rad=0.4m

v (linear velocity) = r (radius of circle) * omega (angular velocity)

lets rearrange

linear velo (2.214 m/s = 0.4m* angular)

2.214 / 0.4

=5.535 rad/sec

initial angular velo = 0

final angular veloc=5.535

time=0.225756

formula=

angular acceleration = initial angular velo. (0) - final angular acc. (5.535) / t (0.225756)

angular acceleration=24.52 rad/s^2

**c) Angular to velocity**Dia=0.8m .. rad=0.4m

v (linear velocity) = r (radius of circle) * omega (angular velocity)

lets rearrange

linear velo (2.214 m/s = 0.4m* angular)

2.214 / 0.4

=5.535 rad/sec

**d) Angular acceleration of the drum**initial angular velo = 0

final angular veloc=5.535

time=0.225756

formula=

angular acceleration = initial angular velo. (0) - final angular acc. (5.535) / t (0.225756)

angular acceleration=24.52 rad/s^2
