Answer plz
A bullet with mass 20 grams and velocity 100 m/s collides with a wooden block of mass 2 kg. The wooden block is initially at rest, and is connected to a spring with k = 800 N/m. The other end of the spring is attached to an immovable wall. What is the maximum compression of the spring?
A bullet with a mass mb=12.3 g is fired into a block of wood at velocity vb=245 m/s.
A bullet with a mass mb=12.3 g is fired into a block of wood at velocity vb=245 m/s. The block is attached to a spring that has a spring constant k 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 of the wooden block.

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...
A bullet with a mass mu = 11.9 g is fired into a block of wood at velocity up = 253 m/s.
A bullet with a mass mu = 11.9 g is fired into a block of wood at velocity up = 253 m/s. The block is attached to a spring that has a spring constant k 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 mw of the wooden block.
