A man is driving his 4.5 m long automobile at 90 kph when the traffic signal in front of him changes to yellow. He is 55 m. from the intersection when he applies the brakes after 1.5 second reaction time. If the car can decelerates at a rate of 3.2 m/s2, at what velocity will he be moving when he reaches the intersection? If the yellow light is 5 seconds long, where will the man be when the light turns red? Assuming he will continue through at the speed found in part when the light changes to red. How long will the light have red when he clears the intersection having a width of 20m? Answer the problem and show complete solution please

During a routine flight in 1956, test pilot Tom Attridge put his jet fighter into a 20 dive for a test of the aircraft’s 20 mm machine cannons. While traveling faster than sound at 4000 m altitude, he shot a burst of rounds.Then, after allowing the cannons to cool, he shot another burst at 2000 m; his speed was then 344 m/s, the speed of the rounds relative to him was 730 m/s, and he was still in a dive. Almost immediately the canopy around him was shredded and his right air intake was damaged.With little flying capability left, the jet crashed into a wooded area, but Attridge managed to escape the resulting explosion. Explain what apparently happened just after the second burst of cannon rounds. (Attridge has been the only pilot who has managed to shoot himself down.)

You are driving a car along a straight road at 133 kph. Suddenly, you saw a cat crossing the road and you apply the brakes decelerating the car at a constant rate of -49.5 m/s2. If your reaction time is 1.75 seconds, what is the shortest stopping distancefrom the moment you see the cat? Illustrate the problem.

You are to drive to an interview in another city at a distance of 300km on an expressway. The interview is 11:15 in the morning and you plan to drive at 100kph so you leave at 8 in the morning to allow some extra time. You drive at that speed for the first 100km, but then construction work forces you to slow to 40kph for 40km. What would be the least speed needed for the rest of the trip to arrive in time for the interview?
