- In Michael Johnson's world-record 400 mm sprint, he ran the first 100 mm in 11.20 ss; then he reached the 200 mm mark after a total time of 21.32 ss had elapsed, reached the 300 mm mark after 31.76 ss, and finished in 43.18 ss. During what 100 mm segment was his speed the highest?You and a friend ride your bikes to a restaurant across town. Both of you start at the same instant from your house, you riding 10 m/s and your friend riding 12 m/s. During the trip your friend has a flat tire and that takes him 8 minutes to fix. He then continues the trip at the same speed of 12 m/s. If the distance to the restaurant is 10 km, who gets there first?A caterpillar's speed decreases from 0.50cm/s to 0.25cm/s at a rate of -0.04cm/s2 as it climbs a leaf. How quickly does the caterpillar undergo metamorphosis?
- An object located at ?⃗0 = (1, 1) ? is displaced by Δ?⃗01 = −2?̂ − 5?̂ ? The object is then displaced by Δ?⃗12 = 3?̂ + 2?̂ ? a) Draw a picture b) What is the final position (?⃗2) of the object? c) How far did the object travel during each displacement? (?: 5.39 ?; 3.61 ?) d) What is the total distance travelled by the object? (?: 9 ?) e) How far did the object end up from where it initially started?(?: 3.16?)Two students are discussing the motion of an object as it falls close to the earth. Jerry makes the following statement: “The velocity of an object when it is falling close to the earth never changes because acceleration due to gravity is constant. “ Susan does not agree with Jerry. Which reason below should Susan give to Jerry to correct his misconception?Two locomotives 70 kilometers apart are travelling on the same track towards each other, Engine A moves at 22 kilometers per hour east and engine B moves at 13 kilometersper hour west. At the instant both trains begin moving, an annoying mutant fly beginsflying from engine A towards engine B at 33 kilometers per hour . The instant it touchesB, it turns around and flies back. It goes on this way until the two locomotives collideand the mutant fly is finally squashed. So, before its untimely demise, a) what is the total distance the fly flew? b) the time it took till it was eliminated and c) the average velocity of the fly? how can i find this please
