Two masses collide inelastically in two different kind of collisions. In the first collision, mass 1 with a mass of 11 kg is moving at 20.9 m/s in the positive x direction and collides with mass 2 with a mass of 4 kg moving at 11.9 m/s in the positive x direction. In the second collision, mass 1 is moving at 20.9 m/s in the positive x direction and collides with mass 2 moving at 11.9 m/s in the negative x direction. If both collisions take place in a time of 0.36 seconds, how much more average force is exerted on mass 2 by mass 1 in the second collision as opposed to the first collision? Answer in Newtons.

two skaters collide and embrace, in a completely inelastic collision. boomer, whose mass is 83 kg, is originally moving east with v=6.2km/hr. sooner whose. mass is 55kg, is originally moving north with v=7.8km/hr. (a) what is the velocity of the couple after impact? (b) what is the velocity of the center of mass of two skaters before and aafter collision? (c) what is the fractional change in the Kinect energy of the skaters because of the collision?

Set up a two particle, totally elastic collision. Make the two particles have different masses. Analyze the collision (determine initial and final velocities of the two particles) in three different frames. One frame must be the center of mass frame, one frame must be co-moving with one of the particles before the collision, and the third frame is up to you. In each frame calculate the change in kinetic energy for each particle and compare these values. That is, does...

Two railroad boxcars collide on a horizontal part of track. The first boxcar has a mass of m1 = 60 000 kg and has an initial velocity of v1i = 1.00 m/s (towards the second boxcar). The second boxcar has a mass of m2 = 80 000 kg and is initially at rest. a) What is the speed of the boxcars after the collision occurs, if a locking mechanism connects them as soon as they collide? b) What percentage of...

Two low-friction physics demo carts collide on a horizontal track. The first cart, with a mass of 0.154 kg , is moving to the right with a speed of 0.810 m/s . The second cart, with a mass of 0.299 kg , is moving to the left with a speed of 2.21 m/s . The carts collide in an elastic collision, such that the total kinetic energy after the collsion is equal to the total kinetic energy before the collision....

Two asteroids collide in space. The collision is not completely inelastic--the asteroids pull apart and continue on their way. Their masses are 8.7 X 108 kg for Asteroid A and 3.4 X 108 kg for Asteroid B. Treat Asteroid A as being initially at rest. Asteroid B, moving at high speed, strikes Asteroid A and moves from the collision at a speed of 7300 m/s in a direction 48 degrees from its original path. Meanwhile, Asteroid A moves away from...

The force vs. time graphs for two collisions are shown. Which collision has the largest impulse?

The force vs. time graphs for two collisions are shown. Which collision has the largest impulse? The impulses are the same. The impulse for collision 2 since it lasts longer. The impulse for collision 1 since it has the larger maximum force. Cannot be determined since the initial an final speeds are unknown. Cannot be determined since the masses are unknown.
