## Homework Statement

A child with poor table manners is sliding his 240 g dinner plate back and forth in SHM with an amplitude of 0.110 m on a horizontal surface. At a point a distance 7.00×10−2 m away from equilibrium, the speed of the plate is 0.350 m/s

1.What is the period?

2.What is the displacement when the speed is 0.160m/s?

3.In the center of the dinner plate is a carrot slice of mass 10.8 . If the carrot slice is just on the verge of slipping at the end point of the path, what is the coefficient of static friction between the carrot slice and the plate?

Take the free fall acceleration to be 9.80 .

## Homework Equations

T=2pi(m/k)^1/2

x=Acos(omega*t+phi)

A=(x0^2+V0^2/omega^2)^1/2

## The Attempt at a Solution

I don't know how to find the angular frequency or the force constant so I'm not sure how to find the period. Also I am confused about the amplitude in SHM equation because I'm not sure what X naught and V naught are.
