- An atomic nucleus suddenly bursts apart (fissions) into two pieces. Piece A, of mass m 4, travels off to the left with speed v4. Piece B, of mass mB, travels off to the right with speed v B.A baseball is thrown vertically upward and feels no air resistance. It reaches a maximum height and turns back downwards. As it is moving downwards O its gravitational potential energy is not conserved, buts its momentum is conserved. O both its momentum and its kinetic energy are conserved. O its momentum is not conserved, but its mechanical energy is conserved. O its kinetic energy is conserved, but its momentum is not conserved. O both its momentum and its mechanical energy are conserved.In a perfectly inelastic one-dimensional collision between two objects, what initial condition alone is necessary so that a the system is gone after the collision? O The objects must have momenta with the same magnitude but opposite directions. medi ume O The objects must have the same mass. O The objects must have the same velocity. O The objects must have the same speed, with velocity vectors in opposite directions. AC
- Is the following statement true? If not, why? Within the system, both the momentum and kinetic energy are conserved during each of the collisions ( spring-loaded elastic, hoop spring, and putty collisions).A 0.430-kg blue bead slides on a frictionless, curved wire, starting from rest at point O in the figure below, where h = 1.50 m. At point O, the blue bead collides elastically with a 0.640-kg green bead at rest. Find the maximum height the green bead rises as it moves up the wire.The 1-kg ball is thrown at the suspended 10-kg block with a velocity of 4 m/s. If the coefficient of restitution between the ball and the block is e=0.8, determine the maximum height h to which the block will swing before it momentarily stops. 4 m/s В h A
- Doing some physics homework and am kind of stumped here!Sometimes, two objects of different mass have the same speed. Other times, they have the same momentum. Which of the following is true about their kinetic energies. O The lighter has the greater kinetic energy in both cases With equal speeds, the heavier has the greater kinetic energy. With equal momenta, the lighter has the greater kinetic energy. O We can't tell from the information given. With equal speeds, the lighter has the greater kinetic energy. With equal momenta, the heavier has the greater kinetic energy. O The heavier has the greater kinetic energy in both cases.The 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?
