- Part A A 22-g bullet traveling 260 m/s penetrates a 1.6 kg block of wood and emerges going 130 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges? Express your answer to two significant figures and include the appropriate units.

That is, compare and contrast the momentum and kinetic energy before and after an inelastic collision.Block "P" of mass Mp slides along an x-axis on a frictionless floor with initial speed Vp,i = 4 m/s. Then it undergoes a one-dimensional collision with stationary block "S" of mass Ms = 0.5 Mp. Next, block "S" undergoes a one dimensional collision with stationary block "U" of mass Mu= 0.5 Ms. Assume that kinetic energy is conserved in each collision. P S ४
- Problem 1 (use impulse and momentum method) The 150 kg box is subjected to forces as shown. If it starts from rest, determine its speed after travelling for 10 seconds under the effect of those forces. The coefficient of kinetic friction between the box and the floor is 0.3. USE WORK AND ENERGY PRINCIPLE 1000 N 800 N 30Solve number 2The ball only loses energy during the collisions. Energy is conserved between collisions. We will denote E the total energy of the ball after the first collision, E2 the total energy of the ball after the second collision, and in general, En will represent the total energy of the ball after the nth collision. Consider the floor to be the reference for zero potential energy. Question 4 a. Find the coefficient of restitution in terms of the ball's kinetic energy just before and just after the nth collision (n > 2). b. If the coefficient of restitution is e = 0, what does that imply about the energy lost during the collision? c. If the coefficient of restitution is e = 1, what does that imply about the energy lost during the collision?
