An animal-rescue plane flying due east at 54 m/s drops a bale of hay from an altitude of 52 m . The acceleration due to gravity is 9.81 ms2 . If the bale of hay weighs 195 N , what is the momentum of the bale the moment it strikes the ground?

The slope of a velocity time graph over any interval of time gives the during that interval

An object weigh 40n in air ,weigh 20n when submerged in water,and 30n when submerged in a liquid of unknown liquid density.what is the density of unknown of liquid?

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
