Week 5 Fall 2019 Two person race with acceleration and deceleration 14 of 15 IReview | Constants Mary and Sally are in a foot race (see figure (Figure 1)). When Mary is 22 m from the finish line, she has a speed of 4.0 m/s and is 5.0 m behind Sally, who has a speed of 5.0 m/s. Sally thinks she has an easy win and so, during the remaining portion of the race, decelerates at a constant rate of 0.44 m/s2 to the finish line. Part A What constant acceleration does Mary now need during the remaining portion of the race, if she wishes to cross the finish line side-by- side with Sally?

Physics 1 Constant Acceleration 2-Object Problems 1, A truck is stopped at a stoplight. When the light turns green, the truck accelerates at 2.5 m/s². At the same instant, a car passes the truck going a constant speed of 15 m/s. Where and when does the truck catch up with the car? 180m, 12s 2. During a demolition derby, 2 cars are initially facing each other so they willI be moving in opposite directions. The red car accelerates from rest at 3m/s?. The green car, initially moving at 4m/s, accelerates at 1.8 m/s². If they start 100m from each other, where will they collide? 5.68s at 48.4m 3. During a demolition derby, 2 cars are initially facing each other so they will be moving in opposite directions. The red car, initially traveling at 8m/s, increases speed by accelerating at 3m/s2. The green car, initially moving at 4m/s west, decreases speed with an acceleration of 0.4m/s2. If they start 100m from each other, where will they collide? 5.3s at 84.5m A ball is dropped from 50m above…
Short computation The position of an object as a function of time is given by x(t) = bt4 - ct² + et, where b = 7.9 m/s4, c = 9.42 m/s², and e = 6.58 m/s. What is the object's instantaneous acceleration a when t = 0.3 s? a = m/s² 4 Remember to include a "-" if the acceleration turns out to be negative. Do not include a "+" for a positive value. Report your numerical answer below, assuming three significant figures.

Lolliguncula brevis squid use a form of jet propulsion to swim -- they eject water out of jets that can point in different directions, allowing them to change direction quickly. When swimming at a speed of 0.15 m/s or greater, they can accelerate at 1.2 m/s2. Determine the distance the squid has traveled while accelerating.
Problem 6 CyclistA cyclist in a race has a speed v2 and is a distance d behind another cyclist traveling at speed v1. (a)Assuming v2 > v1, sketch a position plot with both cyclists on it. (b) What is the minimum distance thatmust be left in the race (for the cyclist in the front) to be caught? (c) Looking at your answer/expressionfrom the previous part, what happens when v1 = v2? Does this make sense? How do I set up?
Problem 5 Running RaceA running race has a total distance d. The winner runs at a steady speed of v0 and the second placefinisher runs at a speed that is 4/5 of the winner’s speed. (a) How much time passes between each runnerfinishing? (b) The winner didn’t realize they pass the finish line. What is the total distance the winnerhas ran when the second place finisher finishes? (c) Sketch a single position plot with curves for bothrunners on it. Draw a horizontal line to represent the finish. How do I set up?
