Answer to Question #278929 in Classical Mechanics for joseph

Question

1. The large water truck releaser water at the rate of 2400 liters/min through the 80-mm-diameter pipe. if the depth of the water in the truck is 1.5 m, determine the frictional force the road has to exert on the tires to prevent the truck from rolling.

2. The 80-kg man stands on the scale. If the bucket of water has a mass of 10 kg, and water is flowing into it at 0.001 m3/s from a 20-mm-diameter hose, determine the reading on the scale at this instant. Assume the bucket is large so that the rate at which the level of water in the bucket is rising can be neglected.
