An instructor fires an arrow into a wooden block suspended by strings, as shown. If the mass of the arrow is 1/10 the mass of the block, what is the momentum of the arrow relative to the momentum of the block after the arrow has fully penetrated the block and is moving with it? a.) The momentum of the arrow is ten times that of the block. b.) The momentum of the arrow is 1/100 times that of the block because the kinetic energy is 1/2mv2. c.) The momentum of the arrow is 1/10 that of the block. d.) The momentum of the arrow is 100 times that of the block because the kinetic energy is 1/2mv2. e.) The momenta are the same.
