A bullet of mass mm = 0.0010 kgkg embeds itself in a wooden block with mass MM = 0.999 kgkg, which then compresses a spring (kkk = 130 N/mN/m ) by a distance xxx = 0.048 mm before coming to rest. The coefficient of kinetic friction between the block and table is μμ = 0.50.a.What is the initial velocity (assumed horizontal) of the bullet?Express your answer using two significant figures.b. What fraction of the bullet's initial kinetic energy is dissipated (in damage to the wooden block, rising temperature, etc.) in the collision between the bullet and the block?

Question

A bullet of mass mm = 0.0010 kgkg embeds itself in a wooden block with mass MM = 0.999 kgkg, which then compresses a spring (kkk = 130 N/mN/m ) by a distance xxx = 0.048 mm before coming to rest. The coefficient of kinetic friction between the block and table is μμ = 0.50.

What is the initial velocity (assumed horizontal) of the bullet?

Express your answer using two significant figures.

What fraction of the bullet's initial kinetic energy is dissipated (in damage to the wooden block, rising temperature, etc.) in the collision between the bullet and the block?
