The table below shows data of sprints of animals that traveled 75 meters. at each distance marker, the animals' times were recorded. which animal moves with non-accelerated motion? time at distance markers animal 25 meters 50 meters 75 meters animal 1 3 seconds 4.5 seconds 5 seconds animal 2 4.5 seconds 5 seconds 5.25 seconds animal 3 3.5 seconds 7 seconds 10.5 seconds animal 4 5 seconds 10 seconds 13 seconds animal 1 animal 2 animal 3 animal 4

Ineed asap! list 3 examples in which friction us or makes things easier in our daily life. explain the effect of friction for each. *make sure you explain the effect of friction for each example! *

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)

5g of ammonium nitrate was dissolved in 60g of water in an insulated container. the temperature at the start of the reaction was 23.0°c and at the end it was 19.0°c. calculate the energy absorbed by the reaction.
