a) An object of mass 0.60kg tied to the end of a rope is whirled in a horizontal circle of radius 2.0m with a constant speed of 10m/s. Find the tension in the string.

  

Answers


Alice
a) m=0.60kg
r=2.0m
v=10m/s
T=(mxvxv)÷r=(0.60x10x10)÷2
=30N

b) max=mg+((mxvxv)÷r)
=(0.60x10)+30= 36N

min=((mxvxv)÷r)-mg
=30-(0.60x10)= 24N
