apparent weight= 55N-densitywater*g*volumestone
30=55-densitywater*g*volumestone
solve for volume stone
volumestone= 25/(densitywater*g)
density of STone= massstone/volume
= (55/g)/(25/densitywater*g)=55/25 *densitywater
A book is placed on a horizontal wooden plane that is undergoing simple
harmonic motion with an amplitude of 1.0 m. The coefficient of friction
between the book and the horizontal wooden plane is given by = 0.5.
Determine the frequency of the horizontal wooden platform when the book
is about to slip from the horizontal wooden plane.
