An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first sec's the car, the locomotive is 160 m from the crossing and its speed is 29 m/s. If the engineer's reaction time is 0.66 S. what should be the magnitude of the mini mum deceleration to avoid an accident? Answer in units of m/s

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).
