Textbook Question
Chapter 12.1, Problem 4cT
A syringe is used to remove some water from the left side of the U-tube. The water level on the left side is seen to be lowered, butthe water level on the right does not change.
Consider the following student dialogue:
| Student 1: | “The pressure at point F must now be higher than atmospheric pressure because the water there is being pushed up against the stopper.” |
| Student 2: | “I think that the pressure at point E must be the same as at point A because they are at the same level. These points are both at atmospheric pressure. So the pressure at point F is lower than atmospheric pressure because know that pressure gets less as you go up.” |
| Student 3: | “But water is more dense than air so the pressure at F cannot be less than atmospheric pressure.” |
With which student(s), if any, do you agree?

A block of mass m₁ = 10.0 kg is connected to a block of mass m₂ = 34.0 kg by a massless string that passes over a light, frictionless pulley. The 34.0-kg block is connected to a spring that has negligible mass and a force constant of k = 200 N/m as shown in the figure below. The spring is
unstretched when the system is as shown in the figure, and the incline is frictionless. The 10.0-kg block is pulled a distance h = 22.0 cm down the incline of angle 0 = 40.0° and released from rest. Find the speed of each block when the spring is again unstretched.

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance yo, and then helps to
support any additional load. Consider a leaf spring constant of 5.45 × 105 N/m, helper spring constant of 3.60 × 105 N/m, and y = 0.500 m.
