Homework Statement A jet of water going through a nozzle is deflected by a flat plate. Get Q, Velocity, Force The volumetric flow rate of water through the nozzle is 10 Litres in 7 seconds The water temperature is 20 degrees celcius. We are using a flat plate so theta = 90 degrees...

I found a really good website which went a long way in answering my question: http://www.lastufka.net/lab/cars/why/pit.htm

I wasnt sure where to post my question. Here goes: I have a car with 4 wheels and one motor. The motor drives an axle connected to the back wheels. The total mass of the car is 1000kg Each wheel weighs 20kg and is a solid cylinder The effective frictional force is 0.2 The radius of the...
