A 1100 kg car travelling south at 8 m/s collides with a 1300 kg car travelling as 10 m/s [N] during an exciting demolition derby. a)  If they become coupled together in the collision, what is their velocity immediately after impact? b)  After the collision, they slide for 10m before coming to a stop. How much time did it take them to stop?

A 1500kg sport car is moving westbound at 20m/s on a level road when it collided with a 4000kg truck driving east on the same road at 15m/s. The two vehicles remain locked together after the collision.   a)what are is the magnitude of the velocity of the two vehicles just after the collision?

The Hulk (200kg of pure angry muscle)collides head-on with a truck (2500kg). If the Hulk was running at 10.0m/s and the truck was moving at 15.0 m/s in the opposite direction, after they stick together, what is their speed (in m/s)? Either the Hulk or the truck needs a negative initial velocity.

Two cars each with a speed of 30 m/s are sliding on frictionless ice at an intersection and collide. Car #1 has mass 1400 kg and Car#2 has mass 1300 kg. The cars stick together after colliding. A) What is the angle the combined mass comes off the collision at ? B)What is the speed of the combined mass?

A 2.5 kg car is moving towards the right at 4 m/s collides head-on with 6.5 kg car moving towards the left at 2 m/s, and they stick together. What is the velocity of combined cars after the collision?

Two water ballons of 0.5kg collide and bounce off each other. Before the collision, one water ballon moved east at a speed of 2.5 m/s. After the collision one moves west at a speed of 1.5m/s. What is the velocity of the other water ballon? 1.5 m/s west1.5 m/s east1 m/s west1m/s east

In the railroad freight yard, an empty freight car of mass m rolls along a straight level track at 1.20 m/s and collides with an initially stationary, fully loaded boxcar of mass 5.80m. The two cars couple together on collision.   a.)What is the speed of the two cars after the collision? b.)Suppose instead that the two cars are at rest after the collision. With what speed was the loaded boxcar moving before the collision if the empty one was moving at 1.20 m/s?

if a stationary 3.2 obect explodes so that: a. one part that is 1.5 kg goes left with 2.6 m/s , what is the mass and velocity of the other part? b. One part that is 1.0 kg goes North at 3.4 m/s and one part that is 1.2 kg goes West at 3.0 m/s, what is the mass and velocity of the third part?

Questions 1.-4. refer to a head-on collision between two balls with the following initial values: Before Collision m2 V Ix 3.5 kg 4.5 kg 5.0 m/s -2.0 m/s 1. What is the total momentum (in kg m/s) of the system? 2. If the two balls stick together, what is their common speed (in m/s) after they collide? 3. How much kinetic energy (in joules, positive number) was lost in this collision? 4. If the two balls do not stick together, and the first ball moves at vịx = -1 m/s after they collide, what is the speed (in m/s) of the second ball?

A car (mass = 1110 kg) is traveling at 31.2 m/s when it collides head-on with a sport utility vehicle (mass=2900 kg) traveling in the opposite direction. In the collision, the two vehicles come to a halt. At what speed was the sport utility vehicle traveling? vo, car VO, SUV Before collision After collision
