The questions are from my physic lab. It is about projectile motion. The report is due tomorrow so if you can finish today that would be very appreciated. thank you
1. Imagine that a smooth ball exits the launcher with a great deal of spin. You may select the angle of the spin. What would happen to the ball's trajectory? Offer an explanation as to why.
2. Now imagine a baseball exits the launcher with a great deal of spin. You may select the angle of the spin. What would happen to the ball's trajectory? Offer an explanation as to why.
3. Name two modifications that could be done to the experiment to minimize uncertainty due to air resistance.
4. If you were to drop a ball from an airplane at 30000 ft, eventually the ball would reach a constant speed even though gravity still pulls on it. Why?
A student presses a book between his hands, as the drawing indicates. The forces that he exerts on the front and back covers of the book are vertical to the book and are horizontal.

An aluminum wing on a passenger jet is 32 m long when its temperature is 26°C. At what temperature would the wing be 8 cm (0.08 m) shorter?
The effective area of each plate of a parallel plate capacitor is 2.4 m^2. The capacitor is full with neoprene rubber (k =6.4). When a 3.0 V potential dissimilarity exists across the plate of the capacitor, the capacitor stores 5.0 μC of charge. Deci..
Having read this chapter, would you change your choice about whether or not Germany's decision is a good move? Are we primarily basing our decision on the events at Fukushima? should we be concerned with increased coal use? what question should be..
