1. The problem statement, all variables and given/known data 1. While descending at a constant speed of 1.0 m/s, a scuba diver releases a cork, which accelerates upward at 3.0 m/s2. What is the diver’s depth when the cork reaches the surface 2.0 s later? 2. A car with a velocity of 27 m/s slows down at a rate of - 8.5 m/s2 to a stop in a distance of 43 m on a dry road. The same car traveling at 27 m/s slows down at a rate of -6.5 m/s2 to a stop on a wet road. a. How much farther does the car travel on the wet road before coming to a stop? b. What maximum car speed will allow the car traveling on the wet road to stop in a distance of 43 m? 3. A car traveling at 14 m/s encounters a patch of ice and takes 5.0 s to stop. a. What is the car’s acceleration? b. How far does it travel before stopping? 4. An accelerating lab cart passes through two photo gate timers 3.0 m apart in 4.2 s. The velocity of the cart at the second timer is 1.2 m/s. a. What is the cart’s velocity at the first gate? b. What is the acceleration? 2. Relevant equations WE NEED TO USE ONE OF THESE EQUATIONS FOR THESE QUESTIONS V= Vo + at d = Vo t + ½ at2 V2 = Vo2 +2ad d = ½ (V + Vo) t g= -9.8 m/s2 3. The attempt at a solution I am sorry. I really have no idea. I have been sick for quite some time and missed a lot of school time. Since we are on break, this was our assignment, I cannot ask the teacher for help. If you can tell me which equation I need to use, I am sure that will help.
