A bullet with mass 25g and initial horizontal velocity 320m=s
strikes a block of mass 2kg that rests on a frictionless surface
and is attached to one end of a spring. The bullet becomes embedded
in the block. The other end of the spring is attached to the wall.
The impact compresss the spring a maximum distance of 25cm. After
the impact, the block moves in simple harmonic motion.
1. What is the frequency of the oscillation?
2. Sketch graphs for the block's position, velocity, and
acceleration as a function of time (x vs. t, v vs. t, a vs. t).
Check to make sure your graphs are consistent.
3. Write an description of what is happening to the energy in this
system
from the time the bullet is red until the block returns to its
starting
position for the rst time. Meaning, tell a story about how the
energy
changes form or moves from one object to another.

A rifle bullet with mass 7.00 g and initial horizontal velocity 290 m/s strikes and embeds itself in a block with mass 0.993 kg that rests on a frictionless surface and is attached to one end of an ideal spring. The other end of the spring is attached to the wall. The impact compresses the spring a maximum distance of 14.0 cm . After the impact, the block moves in SHM. Calculate the period of its motion
wooden block with mass M 3 kg is lying on a horizontal table and is attached to a spring in its equilibrium position. It is hit by a bullet with mass m 5 g which moves horizontally. The bullet remains in the block after colliding with it. The block moves on the table compressing the spring, with spring constant k 50 Nm, a distance 10 cm. The coefficient of kinetic friction uk 0.2. a) Find the elastic energy stored in...
PROBLEM 2 (5 points). Momentum and Mechanical Energy conservation A rifle bullet with mass 150 g strikes and embeds itself in a block with mass 1000 g that rests on a frictionless, horizontal surface and is attached to a coil spring. The initial velocity of the bullet was 700 m/s. The impact compresses the springy a distance x. The spring constant is 550 N/m. The spring is ideal. a) Find the magnitude of the block's velocity (with the bullet stuck...
Item 1 1 of 4 A block of wood connected to a horizontal spring is at rest on a frictionless floor. The mass of the block is 5kg and the spring constant is 125 N/m. A bullet of mass 50g is fired at the block with horizontal velocity of 25 m/s. The bullet gets embedded in the block after hitting it. The block (with the bullet embedded in it) undergoes simple harmonic oscillation as a result of this collision Part...
A bullet mass m1 bounces off a steel block of mass m2 which is resting on a smooth frictionless surface. The initial velocity of the bullet is and the final velocity is -v . A spring with a force constant k is attached to the steel block at one end and attached to a wall at the other. The duration of the impact is delta t . What is the maximum distance through which the spring is compressed
5. A bullet of mass m-0.02 kg was horizontally shot into a wood block of mass mo 8.98 kg, which is attached at one end of a spring with a spring constant k = 100 N/m, as shown in right Figure. After the bullet was embedded into the wood block, the spring was compressed 10 cm. If the coefficient of kinetic friction is 0.2 between the wood block and the surface, find the initial velocity of the bullet. (10 points)
A block of mass 0.992 kg rests on a frictionless horizontal surface. The block is attached to an ideal spring. Calibration shows that a force of 0.75 N is required to compress the spring 0.25 cm. A 8.0-g rifle bullet is fired and embeds itself in the block, compressing the spring 15.0 cm before rebounding. (a) What was the speed of the block just after impact? (b) What was the initial bullet speed?
A block of mass M = 5.60 kg, at rest on a horizontal frictionless table, is attached to a rigid support by a spring of constant k = 6390 N/m. A bullet of mass m = 8.20 g and velocity of magnitude 710 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 block of mass M = 1.94 kg, at rest on a horizontal frictionless table, is attached to a rigid support by a spring of constant k = 110 N/m. A bullet of mass m = 4.7 g and velocity of magnitude 810 m/s strikes and is embedded in the block (Fig. See below). 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)...
