### In an isolated system two roller skaters each with a mass of 100 kg collide skater 1 was initially at rest while skater 2 was moving at 6 ms. They move off together. What is their speed?

They move with a speed of 3 ms^-1.

### In an isolated system two cars each with a mass of 1500 kg collide. Car 1 is initially at rest while Car 2 was moving at 5 ms. What is their combined momentum after the collision?

Law of Conservation of Momentum: The total momentum after the collision is equal to the total momentum before the collission.

### In an isolated system two cars each with a mass of 2000 kg collide Car 1 is initially at rest while Car 2 was moving at 20 ms What is their combined momentum after the collision?

Their combined momentum was 40,000 kg-m/s: 2000kg X 20 m/s= 40000 kg-m/s.

### In an isolated system two cars each with a mass of 1500 kg collide Car 2 is initially at rest while Car 1 was moving at 20 m s What is their final speed?

To find the final speed after the collision, you would need to consider conservation of momentum in an isolated system. If the collision is perfectly elastic, you can use the equation: m1v1i + m2v2i = m1v1f + m2v2f. With Car 2 initially at rest (v2i=0) and Car 1 moving at 20 m/s (v1i=20 m/s), you can solve for the final velocity of both cars.

Their combined momentum was 40,000 kg-m/s: 2000kg X 20 m/s= 40000 kg-m/s.
