Answer:
The ratio of the power generated by the engines are 
(b) is correct option.
Explanation:
Given that,
Mass of Tesla = 2000 Kg
Torque = 400 Nm
Mass of Mercedes = 1.5 M Tesla
The Benz engine produces 50% more torque than the Tesla.
We need to calculate the power generated by the engines 6 seconds after a start from rest
Using formula of power

We know that,



Put the value of F and v in equation (I)


Here, r and t are same for both bodies.

We need to calculate the ratio of the power generated by the engines
Using formula of power

Put the value into the formula


Hence, The ratio of the power generated by the engines are 
Imagine a right angle triangle with the diagonal side being 100m long. Since the angle between the ground and cable is 10 degrees, sin 10 = pole/cable.
Pole length = <span>17.36m
Answer is A, 17.4m.</span>
