Question

A 2.30-kg textbook is forced against a horizontal spring of negligible mass and force constant 300N/m , compressing the spring a distance of 0.260m . When released, the textbook slides on a horizontal tabletop with coefficient of kinetic friction Muk=0.30. Problem 6.81 Part A Use the work-energy theorem to find how far the textbook moves from its initial position before Express your answer using two significant A 2.30-kg textbook is forced against a horizontal spring of negligible mass and force constant 300 N/m, compressing the spring a distance of coming to rest. 0.260m When released. the textbook slides on a horizontal tabletop with coefficient of kinetic friction Muk=0.30. Part A Use the work-energy theorem to find how far the textbook moves from its initial position before Express your answer using two significant L=1.4 m

Explanation / Answer

By work energy theorem,

1/2 kx^2 = uk m g d

where

x = the compression of the spring
d = stopping distance

Plugging in the values and solving for d,

d = 1.50 m [ANSWER]
