Number 7
-(x,y,z) = (6,2,2) f an object of mass, 1 kg, rests on the surface, determine the magnitude of the normal force on the object is the acceleration due to gravity is 9.8 m/s2 (down). Report your answer in N. 29.4 QUESTION 7 The tip of a spinning flagella moves in a circular path and has a initial angular velocity of +15 Hz and an angular acceleration of +3.1 s2. After 14 s of motion, determine the magnitude of the displacement of the tip of the flagella f it's path is 89 nm. For simplicity, you may assume that the tip of the flagella initially begins on thex axis. Report your answer in nm. QUESTION 8 A centrifuge, of radius 24 cm, has a tangential speed of 438 m/s. At the end of the centrifuge, micro-pipettes are Save Click Save and Submit to save and submit. Click Save All Answers to save all answers.Explanation / Answer
angular velocity w = 15 Hz
angular acceleration alpha = 3.1 s^-2
angular displacement theta = w*t + (1/2)*alpha*t^2
theta = 15*14 + (1/2)*3.1*14^2 = 513.8 radian
distance moved = r*theta = 89*10^-9*513.8 = 4.57*10^-5 m <<<<----ANSWER
