It depends on the direction of the crosswind A monkey runs west 4 meters, then realizes he forgot his bananas and 3 meters east. This whole thing takes him 15 seconds. What is the monkey’s velocity? 0.47 m/s 2.14 m/s 9.8 m/s 0.067 m/s Suppose an airplane is flying due north. If a crosswind begins to blow on the plane, what will happen to the plane’s speed? Slow down Speed up Same speed It depends on the direction of the crosswind The acceleration due to the force of gravity on earth is equal to: 9.8 m/s2 9.8 m/s2 * time The same as on the moon Using this PowerPoint break timer This PowerPoint slide uses images, custom animation, and timing to provide a countdown timer that you can use in any presentation. When you open the template, you’ll notice that the timer is set at 00:00. However, when you start the slide show, the timer will start at the correct time and count down by 1-minute intervals until it gets to 1 minute. At that point, it will count down in two 30-seconds intervals to 00:00. To insert this slide into your presentation Save this template as a presentation (.ppt file) on your computer. Open the presentation that will contain the timer. On the Slides tab, place your insertion point after the slide that will precede the timer. (Make sure you don't select a slide.
