Question

HW Chapter 9 Problem 9.03 4 of 19 Review I Constants I Periodic Table The turntable of an old record player has two readings 33 rpm and 45 rpm. Suppose that the rotational acceleration is constant in each of the following cases When the player is turned off and you push the play button, the tumtable attains a speed of 33 rpm in 15 s. Determine the magnitude of the rotational acceleration of the turntable Express your answer with the appropriate units. Value Units Submit Previous Answars Answe x Incorrect; Try Again; 3 attempts remaining Part C You switch the tumtable from 33 rpm to 45 rpm, and it takes about 4.0 s for the speed to change. Determine the magnitude of the rotational acceleration of the tumtable Express your answer with the appropriate units ?

Answer 1

Parct B Initial angulare velocity (wo) = o read/ final frequency = f= 3B repm so angulare velocity (w) = 33x21 ready 60 – 3.457143 readſe time (t) = 158. so who wot at => a = = 0.23048 teada Parete w 3.457143 we u5X2A = 4.7143 readle ta 48, so we wot azt do o 0.314286 read/s2 t & Please rate dear.
