Tennis Ball Testing A tennis ball bouncing on a hard surface compresses and then rebounds. The details of the rebound are specified in tennis regulations. Tennis balls, to be acceptable for tournament play, must have a mass of 57.5 g. When dropped from a height of 2.5 m onto a concrete surface, a ball must rebound to a height of 1.4 m. During impact, the ball compresses by approximately 6 mm. 82. If the ball accelerates uniformly when it hits the floor, what is its approximate acceleration as it comes to rest before rebounding? A. 1000 m/s 2 B. 2000 m/s 2 C. 3000 m/s 2 D. 4000 m/s 2

220 V is supplied to 800 primary turns of an autotransformer. What will the outputvoltage be across 200 secondary turns?
2. A filament transformer has a turns ratio of 1:20. What current must be supplied to theprimary windings if 5 A is required by the filament?
3. The filament transformer in the previous question is supplied with 150 V to theprimary side. What is the secondary voltage?
4. 440 V is supplied to 1000 primary turns of an autotransformer. If the desired outputvoltage is 100 V how many secondary turns must be tapped?
