I'm stuck on these two questions from the same example Part C If the captain of ship A fires a missile, counts 10.0 ss on his watch, and then fires a second missile, how much time Δt will the captain of ship B measure to have passed between the firing of the two missiles? Part D The captain of ship B knows that ship A uses 2-m-long missiles. She measures the length of the first missile, once it has finished accelerating, and finds it to be only 0.872 mm long. What is the speed u of the missile, relative to ship B? Use c=3×108m/s=3×108m/s.
Correct answer s shown Your answer 43.48 It was either rounded differently or used a different number of significant figures than required for this part The "reaction time" of the average automobile driver is about 070 s. (The reaction time is the interval between the perception of a signal to stop and the application of the brakes) An automobile can slow down with an acceleration of 10.8 ft/s Part B Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 55 2 mi/h Express your answer in feet.

Let's say you have a mass of 100 kg. You are orbiting at a radial distance of 10,000 km (10 km, or 10' m) from the center of the Earth (Radius of Earth is ~ 6400 km (6.4 x 10° km, or 6.4 x 10° m), so you are ~ 3600 km above the surface). It takes you two hours and 45 minutes to complete each orbit. 7. What is the acceleration of gravity at your location (in m/s')? (Hint: "G*M" for Earth = 4 x 10") 8. What was your weight (in Newtons) on Earth? WE = 9. What is your weight (gravitational force), compared to what it was on Earth? (in other words, I want the ratio, like your did for # 1-6)

Learning Goal: To practice Tactics Box 1.3 Making a unit conversion. One effective method of performing unit conversions begins by noticing that since, for example, 1 mile 1.609 km, the ratio of these two distances-including their units-is equal to one, so that 1 mile 1.609 km 1.600 km 1 mile 1. Such a ratio of values that is equal to one is called a conversion factor. The tactics described here show how to make a unit conversion using conversion factors. Part B Use the fact that 1 inch = 2.54 cm and convert 39 inches into the equivalent length in centimeters.
