Acceleration The maker of an automobile advertises that it takes 13 seconds to accelerate from 25 kilometers per hour to 80 kilometers per hour. Assume the acceleration is constant.
(a) Find the acceleration in meters per second per seconds.
(b) Find the distance the car travels during the 13 seconds.
Deceleration A car traveling at 45 miles per hour is brought to a stop, at constant deceleration, 132 feet from where the brakes are applied.
(a) How far has the car moved when its speed has been reduced to 30 miles per hour?
(b) How far has the car moved when its speed has been reduced to 15 miles per hour?
(c) Draw the real number line from 0 to $132 .$ Plot the points found in parts (a) and (b). What can you conclude?
hearing question quickly. Father functions E c T equals pick. You go minus 60 squared off 19 lies too. So a is acceleration, which is a double prime and sees the velocity when it's hungry. She was zero. So I know I have to do my double prime. The person concerned with crying t it's been equal three t squared minus 12 t and then the double crime 60 minus 12 which can also be written as six. Factor at six. Get t minus two part eh, R B You have to grab your graphing calculator. So if you draft on your grasp calculator in the White Bulls and you put in the three X square Yeah, um, yeah, dizzy crime green here, my ex plus nine in your graphing calculator, you see, like that and the values are only interested in from want 0 to 5. So the open interval that we're looking for, where it positive or it's moving toe right, which would be positive from here. You hear our graph is negative. So on that interval, it is not moving to the right. So it's all moving from the right from some grow one union from three In the end, that would be. And then our c um, the velocity when intelligence. So Z double premises acceleration. So when acceleration is zero would be a t equals two so that I'm gonna put equals two into my Z prime function, huh? And I get Meg with three.
