A 1210 kg car is driving NE (at 45.0.) at 15.2 m/s when it is struck by a moving 1540 kg car. Afterward, they stick together and move directly east (at 0) at 23.3 m/s. What was the *y*-component of the second car's initial velocity?

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

What part of the ear is names after tools, such as the hammer and the anvil?

Me with this and you will be marked brainliest
