The large container shown in the cross section above is filled with a liquid of density 1.1 x 103 kg/m3 . a small hole of area 2.5 x 10-6 m2 is opened in the side of the container a distance h below the liquid surface, which allows a stream of liquid to flow through the hole and into a beaker placed to the right of the container. at the same time, liquid is also added to the container at an appropriate rate so that h remains constant. the amount of liquid collected in the beaker in 2.0 minutes is 7.2 x 10-4 m3 . a. calculate the volume rate of flow of liquid from the hole in m3/s . b. calculate the speed of the liquid as it exits from the hole. c. calculate the height h of liquid needed above the hole to cause the speed you determined in part (b). d. suppose that there is now less liquid in the container so that the height h is reduced to h/2. in relation to the beaker, where will the liquid hit the tabletop? left of the beaker in the

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
