What is kinematics ???
explain !!!​

Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions). ... In unconstrained, or free, motion, the forces determine the shape of the path.

HOPE IT'S HELPFUL TO YOU

Kinematics is the study of motion of a system of bodies without directly considering the forces or potential fields affecting the motion

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

it doesn't. it was imagined up in the middle ages.
