An acorn at rest falls from an oak tree. The acorn hits the ground with a velocity of 29 m/s. How long did it take the acorn to land? Remember
g=9.8m/s2. DO NOT round numbers. Include units in your answer otherwise it
will be marked wrong.
Whoever answers this question will be the brainliest!!

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
