Two asteroids in outer space collide, then stick together and move as one body afterward. Comment on whether the followi...
Two objects collide and stick together. Which of the following is correct? (A) Neither momentum nor kinetic energy is conserved, (B) Both momentum and kinetic energy are conserved, (C) Momentum is conserved, but kinetic energy is not conserved, (D) Kinetic energy is conserved, but momentum is not conserved
1. Two asteroids collide head-on and stick together. Before the collision, asteroid A (mass 1,000 kg) moved at 100 m/s and asteroid B (mass 2,000 kg) moved at 80 m/s in the opposite direction. Use momentum conservation (make a complete Momentum chart) to find the velocity of the asteroids after the collision. 2. Two asteroids identical to those in (1) collide at right angles and stick together. "Collide at right angles" means that their initial velocities were perpendicular to each...
1. Two objects collide and stick together. Kinetic energy Select one: a. unable to determine with the information. b. Kinetic energy is conserved. c. Kinetic energy is not conserved. d. is conserved only if the environment is frictionless. 2. A ball of mass 0.10 kg is dropped from a height of 12 m. Its momentum when it strikes the ground is Select one: a. 2.4 kg·m/s. b. 1.8 kg·m/s. c. 1.5 kg·m/s. d. 4.8 kg·m/s. 3. If you double the...
Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1200 kg and was approaching at 6.00 m/s due south. The second car has a mass of 800 kg and was approaching at 21.0 m/s due west. (a) Calculate the final velocity of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and y-axis; instead, you must look...
Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1250 kg and was approaching at 6.00 m/s due south. The second car has a mass of 900 kg and was approaching at 17.0 m/s due west. (a) Calculate the final velocity of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and y-axis; instead, you must look...

Kinetic energy is only conserved in an inelastic collision. True False Two objects collide ans stick together. This is an elastic collision. True False Momentum is conserved in both elastic and inelastic collisions. True False
4. Consider two asteroids with masses mi and m2 located in outer space far away from any external forces. m2 is initially stationary but mi travels horizontally to the right towards m2 with an initial speed vo. Let's assume that after the collision the asteroids only move horizontally (in other words we'll assume this problem is purely 1-dimensional) a) Suppose the asteroids stick together after colliding. Find an expression for the final velocity of the asteroids and show that the...
One object is moving and one object is at rest. The two objects then collide in a dimensional, completely inelastic collision. So the two objects stick together after the collision and move off with a common velocity. Momentum of the two-object system is conserved. The masses of the two objects are 5.00 kg and 8.50 kg, respectively. The speed of the moving object masses 5.00 kg before the collision is 22.5 m/sec. Find the final speed of the two-object system...
Two hockey players are skating on the ice when they collide and stick together. Before the collision the 111 kg defensive player is moving at 1.50 m/s in the West direction, and the 93 kg right wing player is moving at 5.90 m/s at an angle of 27.0° South of Westward. a. What type of collision occurs? Will energy be conserved? b. Find the final velocity of the joined hockey players. Answer in POLAR form. c. Calculate the % of...
