apply nitrogen(N) at 50kg per hectare and phosphorus(P) per hectare. assume urea and Di-ammonium phosphate(DAP) fertilizers are the only nitrogen and phosphorus fertilizers available in the store. the experimental plot size of the researcher is 2000m^2. calculate the amount of urea and DAP fertilizers that the researcher has apply to to 2000m^2 experimental plot size. assume N is 46%in urea and and 18% in DAP and P2 O5 is 46% in DAP fertilizer. the atomic weight of P is 31 and O is 16​

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
