(a) The TOUR de France is happening on the 26th June 2021 from BREST to MÜR DE BRETAGNE. Markcycles from Brest to MÜR DE BRETAGNE and Jay cycles to the opposite direction. Knowing that thedistance between BREST and MÜR DE BRETAGNE is approximately 131 Km and that both cyclistsstart cycling towards each other at the same time. Assuming that Mark cycles twice as fast as Jay does.If both cyclists meet one and half hour later, then at what average speed is each one of them traveling?(b) Considering the state of water dams level in Eastern Cape, South Africa. Assume that the area coveredby water weed on Beervlei Dam of Groot River in the Eastern Cape decreases according to the formulabelow.W(t) = Woe-at,where W is the area, in square metres, covered by the water weed after t days and a is a constant tobe determined. Here Wo = 500m? stands for the initial area of water weed. After 10 days, the area is100m?.(i) Find the value of the constant a without simplifying your answer.(ii) Using the expressions of a and the area W to determine the area covered by water weed after 1month and 10 days.

A car traveling 56.0 km/h is 23.0 m from a barrier when the driver slams on the brakes. The car hits the barrier 2.05 s later. a) What is the magnitude of the car's constant acceleration before impact? b) How fast is the car traveling at impact?
A runner with a good awareness of her pace runs along a path of unknown length at a speed of 0.1250.125 mi/min and then walks back to her starting point at a speed of 0.04500.0450 mi/min. She neglects to note her time for each part of her path but does measure the total round-trip time to be 50.050.0 min. How far did she run? (Do not include walking distance.)
Sophia is cruising at 28.0 m/s down Lake Avenue and through the forest preserve. She notices a deer jump into the road at a location 62.0 m in front of her. Ima first reacts to the event, then slams on her brakes and decelerates at -8.10 m/s2, and ultimately stops a picometer in front of the frozen deer. What is Ima's reaction time? (i.e., how long did it take Sophia to react to the event prior to decelerating?
Ilya and Anya each can run at a speed of 7.60 mph and walk at a speed of 3.50 mph . They set off together on a route of length 5.00 miles . Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half. a) Find Anya's average speed. b) How long does it take Ilya to cover the distance? (in minutes) c) Now find Ilya's average speed. Thanks
Colonel John P. Stapp, USAF, participated in studying whether a jet pilot could survive emergency injection. On March 19, 1954, he rode a rocketpropelled sled that moved down a track at a speed of 632 mi/h. He and the sled were safely brought to rest in 1.40 s. Determine in (1) the negative acceleration he experienced and (2) the distance he traveled during this negative acceleration. (Draw the diagram)
Let's assume that East Lake Road runs due East from the Boston Store in Erie, and there are mile markers along it ("Ten Miles from the Boston Store", etc.) A car starts at the 12 mile marker going East at 2 PM, turns around at the 20 mile marker at 3 PM, and stops at the 8 mile marker at 4 PM. What is the total displacement of the car from 2 PM to 4 PM, in miles? (Use "+" for East, and "-" for West) O +4 O-20 O +20 O -4 O none of the answers is correct
You and your family are going on a road trip to visit your recently married cousin in B.C. The total round trip distance is 2100 km. On the way to B.C., you encounter no setbacks and you are able to drive on average at a constant speed. On the way home from B.C., you encounter a snowstorm and your mom has to slow down to avoid getting into an accident. Thus, your average speed decreases by 10 km/h. If the total driving time was 42 hours, what was your average speed on the way to B.C.? Recall distance = speed x time.
