Assertion: A stationary soccer ballis kicked and started to fly through the air. The net work done on the soccer ballis positive. Reason: When a force acts in the same direction as the motion, it does positive work. Select your answer from the choices given below. A. Both Assertion and Reason are true, and Reason is the corred explanation of Assertion. B. Both Assertion and Reason are true, but Reasonis not the correct explanation of Assertion. C. Assertion is true, but Reason is false. D. Assertion is false, but Reasonis true. 2.) A motocross driver is to leap across two hills by driving horizontally at a speed of 28 m/s.

A. 23 m/s C. 32 m/s B.26 m/s D. 34 m/s 3.) A neutral plastic ruler is charged by friction with a neutral silk cloth. The plastic ruler has a stronger hold on electrons than the silk cloth. Which statement is CORRECT? A. The silk cloth is negatively charged, and the plastic ruler is positively charged The protons transferredfrom the plastic ruler to the silk cloth. B. The silk cloth is negatively charged, and the plastic ruler is positively charged The electrons transferred from the plastic ruler to the silk cloth. C. The silk cloth is positively charged, and the plasticruler is negatively charged. The electrons transferred from the plastic ruler to the silk cloth. D. The silk cloth is positively charged, and the plasticruler is negatively charged. The electrons transferred from the silk cloth to the plastic ruler. 4.)

Which of the following statements is CORRECT about the balls' final velocity? A. It is always less than the larger speed. B. It is the average of the two initial speeds. C. It is always greater than the smaller speed. D. It is always less than any of the initial speeds.
