- Two Pushed Boxes: Equal Time A lighter and heavier box are at rest on a frictionless surface. The same force pushes on each box for 1 s. Which box has the larger change in momentum after pushing? Lighter Heavier Insufficient Information Same Submit Answer Tries 0/2 Which box has the larger change in kinetic energy after pushing? Remember, the change in kinetic energy is equal to the work done. Insufficient Information Same Lighter HeavierSummarize what happens to momentum and kinetic energy in an inelastic collision. That is, compare and contrast the momentum and kinetic energy before and after an inelastic collision.Which one among the following statements is CORRECT? A.) Momentum is a scalar quantity B.) In an elastic collision, momentum is conserved but kinetic energy is not C.) In an elastic collision, both momentum and kinetic energy are conserved D.) In an inelastic collision, both momentum and kinetic energy are conserved
- The conservation of energy equation used in the answer was: Conservation of momentum: m1v1 = m1vf1 + m2vf2I believe the conservation of energy equation is:m1v1 + m2v2 = m1vf1 + m2vf2Therefore the answer should be 1.17 m/s.Am I correct? Can someone check my work pleaseA 1,500-kg car and a 3,000-kg SUV truck have the same linear momentum. Which of them has more kinetic energy? O a. O b. O C. Od. Both have the same kinetic energy The SUV truck More information is needed to determine which has more kinetic energy. The carFor each run, determine the kinetic energy (KE = ½ m v2) of the cart just before and after the collision. Enter the values in the Table. Is KE conserved?

Three situations are shown. Identify any that violate the law of conservation of momentum. Note: The bricks on top of the carts have the same mass as the cart. The arrows represent the velocities of the carts. Select all that apply. 0 Before Collision Before Collision Before Collision At Rest At Rest At Rest After Collision After Collision After Collisiona 200g rubber ball traveling with a momentum of 20.0 kg x m/s east rebounds off the wall with a momentum of 18.0 kg x m/s west.
