Hw #M10: Holt p. 58 #3‚ 5; p. 64 # 1‚5 A car accelerates uniformly in a strait line from rest at the rate of 2.3m/s^2. a. What is the speed of the car after 55m? Vf^2= Vi^2+2ad Vf= 2(2.3m/s^2)(55m)= 253m‚ √253m= 16m/s b. How long does it take the car to travel 55m? t= (2∆d)/ (Vi+Vf) t= 2(55m)/ (0+16m/s)= 6.9sec An aircraft has a liftoff speed of 20km/h. What minimum uniform acceleration does this require if the aircraft is to be airborne after a takeoff

wavelengths) of these radiations can tell us a lot about the molecule‚ atom‚ and nucleus under study. Since diffraction-grating spectrometers and other types of radiation spectrometers are widely used in all sciences you should be familiar with the basic physics of such device What does diffraction look like? When light diffracts off of the edge of an object‚ it creates a pattern of light referred to as a diffraction pattern. If a monochromatic light source‚ such as a laser‚ is used to observe diffraction

Because the work is directly proportional to the displacement given a constant force while power is indirectly proportional to work. Therefore we can conclude that power is also directly proportional
