Question

**A 0.85 kg block slides 3.3 m across a frictionless,
horizontal table at 2.2 m/s, moving left. Once the block hits the
spring, it sticks, compressing the spring 70 cm before the block
stops and reverses direction. The block then continues to bounce
back and forth, still attached to the spring. The spring constant
is 8.4 N/m. Ignore air resistance.**

**(b) [3 points] Plot the velocity of the block as a
function of time, with t = 0 when the block is 3.3 m away from the
spring, sliding across the table. Use the same coordinate system
and plot two full oscillations of the spring.**

Answer #1

m1 = 2.2 kg block slides on a frictionless horizontal surface
and is connected on one side to a spring (k = 45 N/m) as shown in
the figure above. The other side is connected to the block m2 = 4
kg that hangs vertically. The system starts from rest with the
spring unextended.
a) What is the maximum extension of the spring?
m
a) What is the speed of block m2 when the extension is 45 cm?

A 1.40 kg block slides with a speed of 0.950 m/s on a
frictionless horizontal surface until it encounters a spring with a
force constant of 734 N/m. The block comes to rest after
compressing the spring 4.15 cm. Find the spring potential, U, the
kinetic energy of the block, K, and the total mechanical energy of
the system, E, for compressions of (a) 0 cm, (b) 1.00 cm, (c) 2.00
cm, (d) 3.00 cm, (e) 4.00 cm

A block with a mass of 0.85 kg rests on a horizontal,
frictionless surface and is attached to an unstretched spring of
length 20 cm. The spring constant of the spring is 9.5 x 103 N/m.
The spring is attached to a wall at its other end. A 7.50-grams,
9-mm-diameter bullet is fired into the block at a speed of 350 m/s
and embeds itself in the block. The system now starts
oscillating.
A. Treat the collision...

A 1.42 kg block is attached to a horizontal spring with spring
constant 3100 N/m . The block is at rest on a frictionless surface.
A 8.40 g bullet is fired into the block, in the face opposite the
spring, and sticks.
Part A
What was the bullet's speed if the subsequent oscillations have
an amplitude of 14.3 cm ?

You push a 3.2 kg block against a horizontal spring, compressing
the spring by 16 cm. Then you release the block, and the spring
sends it sliding across a tabletop. It stops 62 cm from where you
released it. The spring constant is 170 N/m. What is the
coefficient of kinetic friction between the block and the
table?

You push a 4.5 kg block against a horizontal spring, compressing
the spring by 26 cm. Then you release the block, and the spring
sends it sliding across a tabletop. It stops 84 cm from where you
released it. The spring constant is 280 N/m. What is the
coefficient of kinetic friction between the block and the
table?

A man pushes a 4.0 kg block against a horizontal spring,
compressing the spring by 20 cm. Then the man releases the block,
and the spring sends it sliding across a tabletop. It stops 90 cm
from where you released it. The spring constant is 325 N/m. What is
the block–table coefficient of kinetic friction?
A.
0.47
B.
0.97
C.
0.57
D.
0.37

A block of mass M = 5.80 kg, at rest on a horizontal
frictionless table, is attached to a rigid support by a spring of
constant k = 6250 N/m. A bullet of mass m = 8.30 g and velocity of
magnitude 570 m/s strikes and is embedded in the block (the
figure). Assuming the compression of the spring is negligible until
the bullet is embedded, determine (a) the speed of the block
immediately after the collision and (b) the...

A
0.75-kg block slides on a rough horizontal table top. Just before
it hits a horizontal ideal spring its speed is 3.5 m/s. It
compresses the spring 5.7 cm before coming to rest. If the spring
constant is 1200 N/m, the thermal energy of the block and the table
top must have:

A 2.00 kg block slides on a frictionless, horizontal surface
with a speed of 5.10 m/s, until colliding head-on with, and
sticking to, a 1.00 kg block at rest. A) Find the speed of the
combination after the collision. B) The two blocks continue to
slide together until coming in contact with a horizontal spring and
eventually brought to rest. If the blocks compress the spring 10.0
cm, find the spring constant of the spring. C) How much work did...
