hi i am a beginner at physics. my teacher just gave me this problem for a make up work but he did not give me any equations on solving this problem due to some misunderstanding he got mad at me. so here i am stuck..... please help!! A discus thrower (arm length 1.2 m) starts from rest and begins to rotate counterclockwise with a constant angular acceleration of size 2.7 rad/s2. a. How long does it take for the discus thrower's angular speed to reach 5.7 rad/s? b. How many revolutions does it take for the discus thrower's angular speed to reach 5.7 rad/s? c. What is the linear speed of the discus at 5.7 rad/s? d. What is the linear acceleration of the discus at this point? e.What is the size of the discus's centripetal acceleration? f. What is the size of the discus's total acceleration? i searched all over the internet and i still can't find any equations that applys to my questions here is the only question i found.. i don't even know how to use this equation on solving those problems.. O=O(initial)+ W(intial)T + 1/2 XT(square) please begging on my knees for some help on solving this problem!! any helps would be appreciated!!
