A0.0818 kg salt shaker on a rotating table feels an inward frictional force of 0.108 n when it is moving 0.333m/s. what is the radius of its motion? (unit=m)

The required radius of its motion is .

Explanation:

The formula for calculating the required  radius of its motion is given by

Where m= mass  

V= moving velocity

F=frictional force

r = radius of its motion

Then the required radius of its motion is given by

Given that

mas =0.0818 kg

Frictional force= 0.108 N

Moving with Velocity of  = 0.333 m/s

radius of its motion =

Hence the required radius of its motion is r =

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
