Suppose that the amount, in grams, of polonium 210 present in a given sample is determined by the function defined by a(t)equals401e superscript negative 0.032 t, where t is the time in years. find the amount present in a sample of 401 grams after 25 years.

The amount present in a sample of 401 grams after 25 years is

Step-by-step explanation:

we have

A(t) -----> the amount, in grams, of polonium 210 present in a given sample

t -----> the time in years

we know that

To find out the amount present in a sample of 401 grams after 25 years, substitute the value of t=25 years in the equation and solve for A(t)

For t=25 years

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
