Unformatted text preview: Name: Section: Practice Test 4 for Test 2 Practice Test Problem 4.1 [4 pt(s) ] Let’s think back to some of the data analysis we have done in lab. Let’s say we want to calibrate our force sensor using a spring scale. We want to pull on the force sensor with a force of 2 . 0N . If, when we hang a 250g object from the spring scale, it stretches by 5cm , how far do we need to extend the spring when we calibrate the sensor? Sensor Mass Practice Test Problem 4.2 A hockey puck of inertia . 5kg travels at 10 m s to the right and collides with a lump of Silly Putty ( m = 0 . 1kg ) at rest. The combined lump of puck and putty moves at 3 . 5 m s to the right. (a)[4 pt(s) ]What is the energy dissipated in the collision? (b)[3 pt(s) ]Is this collision isolated? Why or why not? (c)[4 pt(s) ]What would be the total convertible energy in this collision, assuming it was isolated? (Do you want to change your answer to (b)?) (d)[5 pt(s) ]If the system is not isolated, and the collision lasted . 1s , what is the average external force exerted on the system?...
