I got this (420+(1/2)1000(V1^2)+1000(0)= 0+(1/2)18(1000)V2^2+1000(9.8)(7.5) so it's 920 V1^2=82500 V2^2 but I don't understand how to get part a and b n how to solve for V1^2 and V2^2 and what does Equation of Continunity: Area1*V1=Area1*V2 mean I mean what is the area...

A house with its own well has a pump in the basement with an output pipe of inner radius 6.4 mm. Assume that the pump can maintain a gauge pressure of 420 kPa in the output pipe. A showerhead on the second floor (7.5 m above the pump's output pipe) has 38 holes, each of ra...

A block of mass m = 3 kg is attached to a spring (k = 28 N/m) by a rope that hangs over a pulley of mass M = 7 kg and radius R = 6 cm, as shown in the figure. Treating the pulley as a solid homogeneous disk, neglecting friction at the axle of the pulley, and assuming the syste...

The pendulum bobs in the figure are made of soft clay so that they stick together after impact. The mass of bob B is 14 times that of bob A. Bob B is initially at rest. If bob A is released from a height h above its lowest point, what is the maximum height attained by bobs A a...

I don't understand what I am doing wrong I plugged in for the 1st one: (.05+.290)(4.75)/(.05+.290) and for second one: 2(.290)(4.75)/(.05+.290) but I get wrong answers!

A 50-g ball collides elastically with a 290-g ball that is at rest. If the 50-g ball was traveling in the positive x-direction at 4.75 m/s before the collision, what are the velocities of the two balls after the collision? 290-g ball: magnitude m/s ? 50-g ball: magnitude m/s ?...
