The question below involves physics concepts like power and force:
The engine in a 1500 kg car has a maximum power output of 200 horsepower, but 25% of the power is lost before reaching the drive wheels. The car has a front profile that is 1.6 m wide and 1.4 m high. The coefficient of rolling friction is 0.02.
a) What is the car's top speed?
b) Is this answer reasonable?

One is unable to determine the reasonableness of a solution until it is obtained....

the priority won't be in a position to be solved without the two some records or assumptions with regard to the distribution of mass on the merry-bypass-around. the least confusing assumption is that the element is a disk, with mass disbursed uniformly; you may calculate the 2d of inertia and multiply via the angular velocity to get the angular momentum. John's angular momentum is 3 meters x 30 kg x 5 m/sec, and you upload this to the previous angular momentum to get the whole. Now you would be able to desire to determine John's 2d of inertia (3 x 30), upload this to the MGR's 2d of inertia, and divide this entire into the whole angular momentum to get the angular velocity.

I can answer "B" without any calculating at all.
The answer is unreasonable.
That is because the engine and transmission have other limits that will restrict the maximums and those limits are not being addressed by the factors listed in the question.
