Asked by mich
a record player is switched from 33rpm to 45rpm.The artable changes speed in 2.0s.Calaculate its average angular acceleration and the average tangential acceleration of a point on the turnable that 15cm from the axis rotation.
Why are you posting in multiple names? Please don't do that.
avgangacceleration=changevelocity/time units are rad/sec^2
Tangental acceleration=angacceleration*radius
units are m/s^2
oh its for my friend so i use her name..and sorry never happens again
thanks for helping us
