Question
Transcribed Image Text:As shown in the figure, the block of
mass m = 1.6 kg is placed on a
horizontal plane and attached to an
ideal spring. The static and kinetic
coefficients of friction between the
block and the plane are gíven in the
figure.the spring has a stiffness of k =
30 N/m and is undeformed when x =
0.the block is launched at x = 0 with
the velocity of 6 m/s to the right.
m=1.6 kg
K=30 N/m
He = 0.3
Hk = 0.2

the block first comes to rest.
а. 1.28 m
b. 1.41m
c. 1.15 m
d. 1.49 m
14.2. Compute the force that tends to
move the block to the left when the
block first comes to rest.
b. 34.76N
d. 39.27N
a. 38.49 N
c. 38.55 N
14.3. Compute the speed of the block
when it reaches x = 0 for the second
time.
