Answer:
The power of sports car is 25 times power of older model car
Explanation:
Consider mass of the two cars are same and is denoted by m.
Kinetic energy of older model car is determine by the relation:
Kinetic energy of sports car is determine by the relation:
....(1)
Power is defined as energy per unit time.
According to the problem, the car has only kinetic energy. So, the power of old model and sports car are determine by the relation:
and
Here P₁ and P₂ are the power of old model and sports car respectively.
The ratio of power of these car is:
Substitute equation (1) in the above equation.
The work done by along the given path <em>C</em> from <em>A</em> to <em>B</em> is given by the line integral,
I assume the path itself is a line segment, which can be parameterized by
with 0 ≤ <em>t</em> ≤ 1. Then the work performed by <em>F</em> along <em>C</em> is
