1) A scooter accelerates at 4.2 m/s2 from rest. How fast is the scooter moving after 3.0 seconds? 2) A soccer ball accelerates from rest and rolls 6.5m down a hill for 3.1 seconds. It is then stopped by a tree. Find final velocity.

This is for physics and I have several more problems like these if someone's interested, i'll post them as well.

Herbivores, carnivores, and omnivores are all types a. decomposers b. producers c. consumers d. biomes

Agas expands from an initial volume of 0.040 m^3 and an initial pressure of 210 kpa to a final volume of 0.065 m^3 while its temperature is kept constant. how much work is done by the system?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
