A car with a mass of 1,350 kg travels at 2.28 m/s and bumps into a stopped car with a mass of 1,200 kg. After the collision, the two cars stick together and move forward. How fast will they both move forward? Round your answer to two decimal places.

1) a child holds two dogs on two separate leads. the dogs are pulling in different directions. one is pulling a force of 20n north and one is pulling 15n eastwards. calculate the resultant force on the child. state the direction. (use the parallelogram of forces) 2) a force of 20n acts horizontally on an object. a second force of 5n acts at 60 degrees to the first one. calculate the resultant force. worth 20 points, need answers asap with method you x
