While driving down a straight road at 70.5 km/h, you pass your physics professor who happens to be out for a jog. He's running at a constant 4.00 m/s, and you decide to slow down and talk physics with him. If you apply your brakes exactly when you pass him on the road, and your car accelerates at 3.58 m/s2 during the breaking, how far do you end up going before he catches up to you?
A driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with an acceleration of 5.60 m/s2 for 4 seconds, making straight skid marks 62.4 m long, all the way to the tree. With what speed does the car then strike the tree?
A blue car travels down a straight road at a constant speed of 18.9 m/s. As they pass a red car, initially stopped on the side of the road, the red car speeds up at a rate of 2.01 m/s2. How much distance (in m) does the blue car travel before the red car overtakes the blue car?

- In the Daytona 500 auto race, a Ford Thunderbird and a Mercedes Benz are moving side by side down a straightaway at 70.0 m/s. The driver of the Thunderbird realizes that she must make a pit stop, and she smoothly slows to a stop over a distance of 250 m. She spends 5.00 s in the pit and then accelerates out, reaching her previous speed of 70.0 m/s after a distance of 390 m. At this point how far has the Thunderbird fallen behind the Mercedes Benz, which has continued at a constant speed?arrow_forwardA police car gets passed by a car traveling at a constant speed of 150.0 km/hr.

- A blue car travels down a straight road at a constant speed of 27.7 m/s. As they pass a red car, initially stopped on the side of the road, the red car speeds up at a rate of 1.61 m/s?. How much distance (in m) does the red car travel before it overtakes the blue car?arrow_forwardHi, I am doing problem number 2 from the end of the chapter questions in my textbook. The problem reads as such: "An 18-year-old runner can complete a 10.0-km course with an average speed of 4.39 m/s. A 50-year-old runner can cover the same distance with an average speed of 4.27 m/s. How much later (in seconds) should the younger runner start in order to finish the course at the same time as the older runner?" I am looking at the solution for the problem and I did everything right except the last step. The solution says to subtract the time found for the 18 year old to run 10km from the time found for the 50 year old to run 10km. However, I divided the anwers I found. Why are we subtracting the answers from one another and not dividing them? Thank you!arrow_forwardA man walks on a straight road from his home to market 2.5 km away with a speed of 5 km/h.

- A sprinter accelerates from rest to a top speed with an acceleration whose magnitude is 3.70 m/s2. After achieving top speed, he runs the remainder of the race without speeding up or slowing down. The total race is fifty meters long. If the total race is run in 7.00 s, how far does he run during the acceleration phase?arrow_forwardA subway train has to travel a distance of 1800 m until it stops at the next station. The train starts from rest and accelerates at a rate of 1.60 m/s2 for 15.0 s. It then runs at a constant speed for some time and finally slows down at a rate of 4.0m/s2 until it stops at the next station. How long did it take to reach the next station?arrow_forwardA cheetah spots a gazelle 60.0 m away. The cheetah accelerates at 7.5 m/s2 toward the gazelle. The gazelle notices the cheetah 2.0 s later and accelerates straight away with an acceleration of 5.2 m/s2. Assuming they both start from rest, how far (in meters) does the gazelle make it before being caught by the cheetah?arrow_forward
