(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
