It collides and couples with another railroadcar of the same mass which was initially at rest. a) What is the speed of the two cars after the collision? b) If the collision happened within 0.02s, how big is the force impacted on the car which was at restinitially?John is in a lab performing an experiment on collision. John takes a 3.0 kg car and sets it moving right with a speed of 1.0 m/s. This car collides with a second car of mass 6.0 kg that John has given a speed of 3.0 m/s left. After the collision, John notes the 3.0 kg car is moving 1.0 m/s left. From this, what would John observe as the velocity of the 6.0 kg car? A. 2.0 m/s to the right B. 0.80 m/s to the left C. 0.80 m/s to the right D. zero m/s E. 2.0 m/s to the left

Two asteroids collide by a glancing blow, but do not actually hit each other, their only interaction being through gravity.D. Two cars with springlike bumpers collide at fairly low speeds.Two particles approach each other with equal and opposite speed, v. The mass of one particle is m, and the mass of the other particle is nm, where n is just a constant factor. Snapshots of the system before, during, and after the elastic collision are shown. m Before nm What is the value of n? Collision V.final m n = After V nm After the collision, the first particle moves in the exact opposite direction with speed 1.30v, and the speed of the second particle, Unm,final, is unknown. nm, finalA child rolls a 4 kg ball with a speed of 6 m/s toward a 2 kg ball that is stationary.

- A 100 g cart initially moving at +0.5 m/s collides elastically from a stationary 180 g cart. Calculate the change in the momentum of the 100 g cart.A 41.0 g marble moving at 2.30 m/s strikes a 29.0 g marble at rest. Note that the collision is elastic and that it is a "head-on" collision so all motion is along a line. What is the speed of each marble immediately after the collision?Sammy with a mass of 20 kg and his mother the mass of 40 kg are at rest 10 m apart. The father of mass 80 kg slides along the path at 15 m/s. He collides with the mother and she bounces ahead to collide with Sammy. If all collisions are perfectly elastic and one dimensional and there is no friction on the straight and level path, calculate the speed of Sammy
