A560-g squirrel with a surface area of 930cm2 falls from a 5.0-m tree to the ground. estimate its terminal velocity. (use a drag coefficient for a horizontal skydiver.) what will be the velocity of a 56-kg person hitting the ground, assuming no drag contribution in such a short distance?

In what direction does an applied force move an object

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )

You have 80 g of 60oc water and 80 g or 10oc water. what is the final temperature when the two are mixed? explain.
