Two soccer balls are rolling across a field. ball 1 has a mass of 1.0 kg, and ball 2 has a mass of 1.5 kg. ball 1 is traveling at a speed of 4.0 m/s, and ball 2 is traveling at a speed of 5.0 m/s. what is the difference in kinetic energy between ball 1 and ball 2?

a. the kinetic energy is equal for both balls.

b. the kinetic energy of ball 1 is 8 j greater than ball 2.

c. the kinetic energy of ball 2 is 10.75 j greater than ball 1.

d. the kinetic energy of ball 2 is 18.75 j greater than ball 1.

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
