Work = force *distance
W= weight *height
W= (10kg) (9.8 N/kg)(2m) = 198 Joules

Answer:
Originally 324 people were infected.
Step-by-step explanation:
Given the function
P = 1620/(1 + 4(0.5)^t)
Where;
P is the total number of people, who have been infected with a contagious virus t weeks after the epidemic began.
t is the number of weeks after the epidemic began.
To determine the number of people who originally have the virus. At this time
t = 0
Therefore, substituting t = 0 into the function of P
P = 1620/(1 + 4(0.5)^0)
P = 1620/(1 + 4)
P = 324 people.
Originally 324 people were infected.
