Water leaves a hose at a rate of 2.0 kg/s with a speed of 20 m/s and is aimed at the side of a car, which stops it. (That is, we ignore any splashing back.) What is the force exerted by the water on the car?
a) On a throw-in, a tennis player hits his 0.075 Kg ball with the racket, providing him with an impulsive force. Assuming that the ball and the racket are in contact for 5 ms and then the ball leaves the racket at a speed of 40 m / s, what would be approximately the average racket force on the ball? Ignore all other forces, including gravity b) Water flows out of a hose at a rate of 1.2 Kg for...
A firefighter is spraying water on a building. Water leaves the hose at 35 m/s and an angle of 30 Degrees above the horizontal. The nozzle of the hose is 1.0 m above the ground, and the building is 22 m away. The building is 40 m tall. a. How much time does it take for the water to reach the building? b. At what height above the ground does the water hit the building? c. In what vertical direction...
7.) A stream of water traveling at 20 m/s at the rate of 600 liters per min. is directed horizontally against a vertical wall. The water spreads out along the wall without splashing back. What force does this stream exert on the wall? Note that the density of water is 1000 kg/cubic meter, and 1 liter = 10(negative 3 power) (cubic meter. (200 N)
Selena uses a garden hose to fill a bucket of water. The water enters the hose through a faucet with a 6.0-cm diameter. The speed of the water at the faucet is 5 m/s. If the faucet and the nozzle are at the same height, and the water leaves the nozzle with a speed of 20 m/s, what is the diameter of the nozzle?
13. A vertical jet of water leaves nozzle at speed of 10 m/s and diameter of 20 mm. it suspends a plate having a mass of 1.5 kg as shown. What is the vertical distance h?
