Answer 1

Answer #1

8.

n times * circumference = linear distance

12* ( pi* d) = 3.5

d = 0.093 m

======

ii)

r = 0.35/2 = 0.175 m

w = ( 2 pi / 60)* 2200

w = 230.27 rad/s

iii)

Linear speed = r w = 0.175* 230.27 = 40.3 m/s

Acceleration, a = v^2/r = 40.3^2 / 0.175 = 9280.5 m/s^2

========

Plz post other problem seperately

Do comment in case any doubt will reply for sure . Goodluck

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
