A 12.0-g bullet is fired horizontally into a 109-g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 144 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 87.0 cm, what was the speed of the bullet at impact with the block?  m/s

A 326- g stationary air-track glider is attached to the end of an air track by a compressible spring with spring constant k = 7.22 N/m (see the figure). A 163- g glider moving at 1.27 m/s collides elastically with the stationary glider. How far does the spring compress? Assume that the air track is very much heavier than the gliders.

A 26-g rifle bullet traveling 240 m/s embeds itself in a 3.7-kg pendulum hanging on a 2.6-m-long string, which makes the pendulum swing upward in an arc. (Figure 1) a)Determine the vertical component of the pendulum's maximum displacement. b)Determine the horizontal component of the pendulum's maximum displacement.

Block A in (Figure 1) has mass 0.800 kg, and block B has mass 2.85 kg. The blocks are forced together, compressing a spring S between them; then the system is released from rest on a level, frictionless surface. The spring, which has negligible mass, is not fastened to either block and drops to the surface after it has expanded. Block B acquires a speed of 1.30 m/s.

A 1.9-kg ball is attached to the end of a 0.6-m string to form a pendulum. This pendulum is released from rest with the string horizontal. At the lowest point of its swing, when it is moving horizontally, the ball collides with a 0.5-kg block initially at rest on a horizontal frictionless surface. The speed of the block just after the collision is 2.5 m/s. What is the speed of the ball just after the collision?

A 5.00-g bullet moving with an initial speed of v₁ = 390 m/s is fired into and passes through a 1.00-kg block as shown in the figure below. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 860 N/m. The block moves d = 5.40 cm to the right after impact before being brought to rest by the spring. (a) Find the speed at which the bullet emerges from the block. m/s (b) Find the amount of initial kinetic energy of the bullet that is converted into internal energy in bullet-block system during the collision.

A bullet with a mass mb=11.9g is fired into a block of wood at velocity vb=257 m/s The block is attached to a spring that has a spring constant kk of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass mwmw of the wooden block.

A 12.0-g bullet is fired horizontally into a 114-g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 141 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 82.5 cm, what was the speed of the bullet at impact with the block?

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.25 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 39.0 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target?

Bullet of mass 105 grams, hits the stationary block of mass 15,190g (originally frictionless surface) and embeds in it. The block then enters a rough surface (coefficient of friction= 0.30) by a distance of 9.0 meters, before coming to stop. Find the speed of the bullet when it hits the block. Use g = 9.8 m/s2 and state your answer in m/s to the nearest tenth of m/s.
