Problem 11 A bullet of mass 0.0020 kg embeds itself in a wooden block with mass 0.991 kg, which then compresses a spring (k = 190 N/m) by a distance 0.055 m before coming to rest. The coefficient of kinetic friction between the block and table is 0.40. Part A What is the initial speed of the bullet? Express your answer in meters per second to two significant figures. ΕΧΕΙ ΑΣΦ Vin = 1.005 Submit Previous Answers Request Answer × Incorrect; Try Again; 7 attempts remaining Part B ? m/s 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? Express your answer using three significant figures. ΜΕ ΑΣΦ AK/K= ?
