The equation of our ellipse is:
(1)
First, let's reduce the equation of the ellipse to the standard form:
To do that, we should divide both terms of equation (1) by 6400, and we get:
This is a vertical ellipse (because ) centered in the origin, and so the distance of its foci from the origin (on the y axis) is given by
Therefore, the position of the two foci is (0,6) and (0,-6)
The car's acceleration will be 0.575 m/s².The unit of acceleration is m/sec².
<h3>What is acceleration?</h3>The rate of velocity change concerning time is known as acceleration.
Given data;
Initial velocity, u= 0 m/s
Final velocity, v= 4.2 m/s
Time elapsed, t = 7.3 seconds.
To find ;
Acceleration, a
The acceleration when the change in velocity is observed by the formula as:
a= (v-u)/(t)
Substitute the given values:
a= (4.2-0)/(7.3)
a=(4.2)/(7.3)
a= 0.575 m/s²
Hence, the car's acceleration will be 0.575 m/s².
