Bullet of mass embeds itself in a

wooden block with mass which then compresses a spring by a distance

before coming to rest. the coefficient of kinetic friction

between the block and table is (a) what is the

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

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .
