An object moving in a straight line with an initial velocity of 12 m/s is found to be moving at 48 m/s after traveling a distance of 75 m. What was its acceleration in m/s2 ?

14.4 m/s2

Change in distance = (velocity final + velocity intial)/2 × change in time

75 = (48+12)/2 × change in time

Change in time = 2.5s

Acceleration = (velocity final- velocity intial)/ change in time

Acceleration =(48-12)/2.5

Acceleration = 14.4 m/s2

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
