If two objects crash into each other, what happens? Are both objects affected? How? If you can, give an example to support your ideas.

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

If a balloon is taken outside on a very cold day, what will occur?
