A bullet of mass m is fired horizontally into a block of wood of mass M lying on a table. The bullet remains in the block and they slide a distance d after the collision. The coefficient of kinetic friction between the wooden block and the table is u. What was the speed of the bullet before the collsion? let m=.020 kg, M=2.00 kg, u=.500, and d=3.00m

A bullet of mass Mb is fired horizontally with speed Vi at a wooden block of mass Mw resting on a frictionless table. The bullet hits the block and becomes completely embedded within it. After the bullet has come to rest within the block, the block, with the bullet in it, is traveling at speed Vf . 1)Which of the following best describes this collision? a)perfectly elastic b)partially inelastic c)perfectly inelastic 2) Which of the following quantities, if any, are...

A bullet of mass 4.3 g is fired horizontally into a 7.4 kg wooden block at rest on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.53. The bullet stops in the block, which slides straight ahead for 1.7 m (without rotation). (a) What is the speed of the block immediately after the bullet stops relative to it? (b) At what speed is the bullet fired?

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...

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 bullet of mass 1.8×10−3 kg embeds itself in a wooden block with mass 0.987 kg , which then compresses a spring (k = 150 N/m ) by a distance 5.5×10−2 m before coming to rest. The coefficient of kinetic friction between the block and table is 0.54. What is the initial speed of the bullet? Vinit==? What fraction of the bullet's initial kinetic energy is dissipated (in damage to the wooden block, rising temperature, etc.) in the collision between...

A bullet of mass 2.0×10−3 kg embeds itself in a wooden block with mass 0.996 kg , which then compresses a spring (k = 120 N/m ) by a distance 4.5×10−2 m before coming to rest. The coefficient of kinetic friction between the block and table is 0.49. A) What is the initial speed of the bullet? B) What fraction of the bullet's initial kinetic energy is dissipated (in damage to the wooden block, rising temperature, etc.) in the collision...

A 1.35-kg wooden block rests on a table over a large hole as in
the figure below. A 4.80-g bullet with an initial velocity vi is
fired upward into the bottom of the block and remains in the block
after the collision. The block and bullet rise to a maximum height
of 20.0 cm.

A bullet of mass 8 g is fired into a 1.2 kg ballistic pendulum (a block of wood acting as the pendulum bob of a thin metal arm attached to a low friction pivot point) that is initially at rest. The bullet exits the block of wood with a speed of 180 m/s and the wooden block swings from its lowest point to a maximum height of 9.2 cm above that location. Determine the velocity of the bullet before it...

A 0.940 kg block is attached to a horizontal spring with spring constant 1600 N/m . The block is at rest on a frictionless surface. A 8.00 g bullet is fired into the block, in the face opposite the spring, and sticks. The subsequent oscillations have an amplitude of 13.0 cm . A) Find the total energy of the oscillator. B) Find the speed of the bullet and block immediately after the collision. C) Find the speed of the bullet...
