An airplane heads due north at 100 m/s being blown by the wind at 500 m/s due East. Draw it's graph. Determine the resultant velocity of the airplane. After several tries of measuring, Lydia gets the results of 2.75, 2.76, 2.30 cm. She realized that the results of measurement is closest to the actual measurement which is 3.25. What is the implication of her measurements? Is it Accurate and precise? I measured the length of cabinet 3 times. The results of my measurements are 3.44 m, 3.55 m, 3.47 m. Afterwards, I compared it to the results with each other. What did I was trying to find out? Is it precision?
Caleb left home and traveled toward the city A at an average speed of 61.3 km/h. Some time later, Kim left traveling in the opposite direction with an average speed of 47.4 km/h. After Caleb has traveled for 1.36 hours they were 147 km apart. Find the number of minutes Kim traveled. Round off only on the final answer expressed in three decimal places.

Answer the following question(s): A student sees her physical science professor approaching on the sidewalk that runs by her dorm. She gets a water balloon and waits. When the professor is 2.0s from being directly under the window about 11m from the sidewalk, she drops the balloon. Finish the story. Instructor Note: There are several ways to reach the correct answer. I generally solve for time to determine if balloon will hit the professor or not based on the given scenario. A formula to use is ?=12??2d=12gt2?d = 1 2 g t 2 where d = distance g = gravitational constant of 9.8 t = time
