An object has a mass of 2kg moving to the right with velocity of 12m/s and collides head on with a stationary object whose mass is 6kg. The collision is perfect elastic so what is the final velocity of the 2kg object and if the final velocity of 6kg object is 6m/s to the right? How do i solve and use the formulas in the pic

Impact extinction 65 million years ago over 50% of all species became extinct, ending the reign of dinosaurs and opening the way for mammals to become the dominant land vertebrates. A theory for this extinction, with considerable supporting evidence, is that a 10-km-wide 1.8×1015kg asteroid traveling at speed 11 km/s crashed into Earth. A) Determine the change in velocity of Earth due to the impact. Mass of Earth is 5.98×1024kg. B) Determine the average force that Earth exerted on the asteroid while stopping it. Assume that stopping distance is 0.60 km (depth of the crater created) C) Determine the internal energy produced by the collision (a bar chart for the process might help). By comparison, the atomic bombs dropped on Japan during World War II were each equivalent to 15,000 tons of TNT (1 ton of TNT releases 4.2×109J of energy).

In the figure, determine the character of the collision. The masses of the blocks, and the velocities before and after, are shown. The collision is___   A)perfectly elastic   B)not possible because momentum is not conserved   C)characterized by an increase in kinetic energy.   D)completely inelastic

The impulse-momentum theorem relates impulse to the change in momentum. You throw a 400 g rubber ball at 10 m/s against a wall. The ball rebounds at 8 m/s.      1. What is the initial momentum? ________ Final momentum? ________ Impulse? ________    2. Given this, is it better for a car to come to a stop or bounce back in a collision? ___________

Two balls with masses 3 kg and 2 kg move toward each other, collide head-on, and stick together after the collision (a perfectly inelastic collision). Before the collision the 3-kg ball moves with a speed of 5 m/s and the 2-kg ball moves with a speed of 10 m/s. Neglect friction. See the figure above.   What is the velocity of the balls after the collision?     a. -2 m/s   b. -1 m/s   c. 3 m/s   d. 5 m/s
