Imagine you are driving around a horizontal circular track (such as a roundabout at an intersection or freeway exit). You are driving at a constant speed of 12.0 km/h, and your circular path has a radius of 17.0 meters.(a) When you are at the southernmost point on the circular track and driving towards the west, what is your acceleration? Give your answer in m/s2The magnitude is m/s2, and the direction is choose from the drop-down listEastNo Direction, since the acceleration is zero. NorthSouthWest(b) When you are at the easternmost point on the circular track and driving towards the south, what is your acceleration?The magnitude is m/s2, and the direction is choose from the drop-down listEastNo Direction, since the acceleration is zero.

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

An automobile steering wheel is shown. what is the ideal mechanical advantage? if the ama is 8, what is the efficiency of the steering wheel?
