hey Mum, i did as u said but i got only the angular velocity,others are wrong. this is how i got my alpha: Torque=m*g*(l/2)=I_CM*alpha. ie taking torque from origin. am i correct? if yes then what might be the problem.

i also tried using I=I_CM+(m*l^2)/4,still my answers were not correct.

hello Damon, i really appreciate that you are sharing your knowledge with us here. please can you solve for part b and c. I followed your procedure. I got my alpha by taking torque at the Origin both using I=I_CM and I=I_CM+I_P. They were all wrong. pleas...

Thanks to everyone that contributed to this, now i can rest :)

Hey Damon, i just want to say thank you for making me believe in myself one more time. i got this but i didn't think my workings were right,so i was scared to key in my answers. Now,i am sooo confident in myself. thank you.

c) 25.33 percent

for a temperature of 20c, a)0.260269. b)54688.24358 and c) 25.33%

glad i could help :)
