The velocity a stroller is pushed from rest, accelerating at 500m/s is 7.5 m/s.
To find the final velocity of the stroller after it has traveled a certain distance while accelerating, one can calculate it using the third equation of motion:
v²-u² = 2as
The third equation of motion is one of the equations used in classical physics to describe the motion of an object with constant acceleration.
Given:
Acceleration, a = 500 m/s²
Distance, s = 6.32 m
The velocity is computed as:
v² - 0² = 2 × 500 × 6.32
v² = 6320
v = 79.5 m/s
Hence, the velocity a stroller is pushed from rest, accelerating at 500m/s is 7.5 m/s.

Answer: a. nasal cavity
Explanation:
The nasal cavity is a external opening of the respiratory tract. This involves two canal like cavities through which air enters the respiratory tract and moves out of the body. These are the two hollow spaces within the nose each of which consists of mucus and lined up with the hairs.
The primary function of the two nasal cavities is to moisturize, warm and filter the air entering the respiratory tract. These cavities filter out environmental contaminants like dust, pollen, molds and others.

B) The momentum before the collision is greater than the momentum after the collision.
C) The momentum before the collision is less than the momentum after the collision.
The car A has a mass of 1200 kg.
The car B has the mass of 1900 kg.
It is given that velocity of car A is given as 22 Km/hr
The car B has the velocity of 25 Km/hr.
Let the mass of two bodies are denoted as
Let the velocity of cars A and B are denoted as
The momentum before collision is-
[Here p stand for momentum.]
We are asked to calculate the final momentum of the system after collision.
The answer of the question is based law of conservation of linear momentum.
As per law of conservation of linear momentum the sum total linear momentum for an isolated system is always constant.Hence irrespective of the type of collision[elastic and inelastic],the momentum of the system is always constant which is a universal truth.
Let after the collision the velocity of A and B are
Hence the final momentum of the system is-
As per the law of conservation of linear momentum, the initial and final momentum must be equal i.e
Hence the option A is right.
