Two blocks of mass m1 = 8.0 kg and m3 = 6.3 kg, connected by a rod of mass m2 = 1.8 kg, are sitting on a very low-friction surface, and you push to the left on the right block (mass m1) with a constant force of (-30 , 0, 0)n. see figure below. (as usual, +x is to the right and +y is up. ignore effects due to friction between the objects)
what is the force f3 exerted by the rod on the block of mass m3?

What is the stall speed at sea level of an airplane that weights 10000 lbs., has a wing area of 300ft^2, and a maximum lift coefficient of 1.4? what is the stall speed if flaps that double cl,max are applied?

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
