Question

A block with mass m = 7.4 kg is attached to two springs with spring constants kleft = 31 N/m and kright = 53 N/m. The block is pulled a distance x = 0.27 m to the left of its equilibrium position and released from rest.

7)

Where is the block located, relative to equilibrium, at a time 1.06 s after it is released? (if the block is left of equilibrium give the answer as a negative value; if the block is right of equilibrium give the answer as a positive value)

8)

What is the net force on the block at this time 1.06 s? (a negative force is to the left; a positive force is to the right)

9)

What is the total energy stored in the system?

A block of mass m = 0.53 kg attached to a spring with force
constant 119 N/m is free to move on a frictionless, horizontal
surface as in the figure below. The block is released from rest
after the spring is stretched a distance A = 0.13 m. (Indicate the
direction with the sign of your answer. Assume that the positive
direction is to the right.)
The left end of a horizontal spring is attached to a vertical
wall, and...

A block of mass m = 0.79 kg is attached to a spring with force
constant 123.0 N/m. The block is free to move on a frictionless,
horizontal surface as shown in the figure. The block is released
from rest after the spring is stretched a distance A = 0.10 m to
the right. What is the potential energy of the spring/block system
0.25 s after releasing the block?

A 200.g block on a horizontal, frictionless surface is located
between two unstrained springs. The spring on the left of the block
has a spring constant of 35N/m and the spring on the right has a
constant of 85N/m. a) How much work must be done by an external
force to displace the block 3.0cm to the left? b) If the block is
released from the above position, how fast will the block be moving
when it returns to the...

a) A block with a mass of 0.600 kg is connected to a spring,
displaced in the positive direction a distance of 50.0 cm from
equilibrium, and released from rest at t = 0. The block then
oscillates without friction on a horizontal surface. After being
released, the first time the block is a distance of 15.0 cm from
equilibrium is at t = 0.200 s.
What is the block's period of oscillation?
_______ s
b) A block with a...
