please help with question 10 2 and 3

g on the electron orbit of radius the yo-yo's tangential speed? Answer in units of m/s. 010 10.0 points The following figure shows a Ferris wheel that rotates 5 times each minute and has a diame- ter of 19 m. 0 points tion of the elec- 0 points ater of a merry- 1.6 m/s cen- the dog's linear 0 points What is the centripetal acceleration of a ts irls a set of keys 9.8 m/s tal acceleration a length of 0.31 rider? The acceleration due to gravity is Answer in units of m/s

Explanation / Answer

10.

angular velocity

W=5 rev/min =5*(2pi/60)=0.5236 rad/sec

centripetal acceleration

a=W2R =0.52362*19

a=5.21 m/s2

-----------------------------------------------------------

centripetal acceleration is

ac=V2/R

=>V=sqrt(acR)=sqrt(2.1*1.4)

V=1.71 m/s

------------------------------------------------

2)

centripetal acceleration

ac=V2/R =(2.01*106)2/(5.03*10-11)=8.032*1022 m/s2

1)mass of electron 9.11*10-31 kg

Central force

F=meac=(9.11*10-31)(8.032*1022)=7.32*10-8 N

3)

ac=8.032*1022 m/s2
