Which model is a physical model? A. A plastic skeleton that shows all the bones of the body
B. A simulation of the history of life on Earth
C. A graph that uses analyzed data to show the spread of a disease
D. A bar graph that shows how many students buy lunch each day

A. Aplastic skeleton that shows all the bones of the body

Explanation:

because physical means like 3D and not on paper or in technology.

total distance/total time

(85 + 82)/(5+3)

167/8

20 just over

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
