2. You can perform a popular trick by dropping any peso bill (Ex. 500 peso bill )lengthwise through the thumb and forefinger of a classmate. Tell your classmate to grab the peso bill as fast as possible and he/she can keep the money if he/she catches it. The length of the peso bill is 15.7 cm and the average human reaction time is about 0.20 s. Will your classmate catch the bill and keep the money? 3. a) A boy throws a stone straight upward with an initial speed of 15 m/s. What maximum height will the stone reach before falling back down? b) What would be the maximum height of the stone if the boy and the stone were on the surface of the Moon, where the acceleration due to gravity is only that of the Earth's? 4. In the figure below, a student at the window on the second floor of a dorm sees his Physics teacher walking on the sidewalk beside the building. He drops a water balloon from 18 m above the ground when the teacher is 1 m away from the point directly beneath the window. If the teacher is 1.7 m tall and walks at a constant velocity of 0.450 m/s, would the water balloon hit her? If not, how close does it come?
