Q. For the normal force to have the similar magnitude at all points on the vertical track, the stunt driver must adjust the speed to be different at different points. Presume, for example, that the track has a radius of 2.40 m and that the driver goes past point 1 at the bottom with a speed of 18.00 m/s. What speed should she have at point 3, so that normal force at the top has the same magnitude as it did at the bottom?

Q. A solid has a volume of 8cm3. When weighed on a spring scale calibrated in grams, the scale indicates 20g. What does the scale indicate if the object is weighed as immersed in a liquid of density 2g/cm3?
