A student throws a heavy red ball horizontally from a balcony of a tall building with an initial speed v0. At the same time, a second student drops a lighter blue ball from the same balcony. Neglecting air resistance, which statement is true?

(A) The blue ball reaches the ground first.
(B) The balls reach the ground at the same instant.
(C) The red ball reaches the ground first.
(D) Both balls hit the ground with the same speed. (E) None of the above statements is true.

(B) The balls reach the ground at the same instant.

Explanation:

Since it is a projectile motion, the time required to reach the ground is given by

t = √2h/g

Where h is the height from which the balls are thrown and g is the acceleration due to gravity.

Since both of the balls were thrown from the same height and the acceleration of both balls are also same they will reach the ground at the same instant.

answer would be d.) i hope this

explanation:

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
