<span>As gas particles are in constant
motion, it exhibit perfect elastic collisions with other particles and travel in straight line in complicated paths. According to <span>Kinetic Molecular Theory, gas is modeled as a
collection of gas particles that are </span>colliding frequently with one another and with the walls of the container
but no energy is lost during the collision.</span>
Explanation:
In the picture, i hope that it's a clear.
A=(Vo-V)/t=(10-0)/0.26=10/0.26=38.46m/s2
F=ma=70*38.46=2692.3N
We use the first equation of motion, to calculate the acceleration of the car
Here, v is final velocity and its value is 100 km/h = 100(1000/3600) = 27 .78 m/s and u is initial velocity as car accelerates from rest so its value zero and t is time taken and its value is given 4.80 s.
Therefore,
.
Now the magnitude of force,
.
Thus, the magnitude of force by passenger experience during the acceleration is 393 .52 \ N.
