1) what would the average acceleration be for a car at a stoplight that speeds up to 20 m/s in 10 seconds (in m/s^2) 2) imagine that a car traveling at 100 m/s must slam on the brakes to avoid hitting a raccoon. if it takes 4 seconds for the car to slow down to a stop, what is its acceleration (in m/s^2)

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

14. a body is projected with velocity vi from a.at the same time another body is projectedvertically upwards from point b withvelocity v2 lies vertically below the highestpoint. both the bodies collide thenv2÷v1is
