Someone please help me it’s due tomorrow 1) How do we calculate the momentum of a race car? What part of this changes during a collision?

2) What happening to the momentum of the car when they crash?

3) how does impulse factor into this?

4) what type of collision is it ( ideally) when cars crash into this SAFER barrier?

Why are graphs useful when interpreting data

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
