An electric skateboarder is travelling west on a path along the river at 5m/s. Å brisk walker on the other side of the riverbank is walking east along a path at 3m/s. The two paths are 40m apart. The skateboarder is initially 600m east of the walker. After 60 seconds, how fast is the distance between the skateboarder and the walker changing? Note: We encourage you to use a scientific calculator for this question. The answer below was rounded to 4 decimal points. 1.6873m/s -5.4891m/s O-7.5895m/s -9.3214m/s

You are a construction worker standing still on 12th Ave N in Fargo, and you watch a minivan drive past at 25 mi/hr eastward. A kid in the back throws a ball at his brother in the front seat at 19 mi/hr. How fast does the ball move, as observed by you? (Positive indicates east, negative indicates west.) ? How fast does the ball move, according to the kid who threw it? If instead the kid in the front seat throws a rock at the kid in the back seat at 19 mi/hr, how fast would you observe the rock to travel?
A “moving sidewalk” in an airport terminal moves at 1.0 m/s and is 35.0 m long. If a woman steps on at one end and walks at 1.5 m/s relative to the moving sidewalk, how much time does it take her to reach the opposite end if she walks (a) in the same direction the sidewalk is moving? (b) In the opposite direction?
Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 20 km to a second toll booth, then another 40 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 60 km. What is the total end-to-end delay? Where is the last car in the caravan after one hour? Your answer must include a distance/specific location, and not only a relative direction.
A runner is moving at 6m/s when they begin to decelerate at 2m/s2 . How far will they travel until they come to a stop? How do I solve this? My professor has it worked to where 6m/s is the final velocity and I don't understand why.
