I'm Wishing To Make A Few Notes About Some Things About Physics , I So Thought in Equation Torricelli, Is An Equation that All Beginner Will See !
The Equation Is An Equation Torricelli kinematic was discovered by Evangelista Torricelli, one whose function is the ability to calculate the final speed of a body in uniform rectilinear motion varied (accelerated motion) without having to know the time interval in which this remained movimento. the great advantage of this equation is that the time factor does not existe.
The equation has the form:
Where and Represent the initial and final velocities of the body, respectively, represents the distance traveled and is the acceleration.
This equation can be deduced from the following equations:
Isolating in the second equation :
And replacing it with the first, We have to :
I ) A motorcycle has an initial speed of and acquires a constant acceleration equal to . Calculate your speed in to cover
II ) A particle initially at rest shall be accelerated continuously at a rate of in the direction of the trajectory. Having driven , its speed is :
Removing the text data, We have :
As we do not know the time of movement applies to equation Torricelli :
III ) A driver is traveling by car on a highway at a constant speed of , when he notices a horse in front of him and decides to stop printing a constant deceleration of per second. Calculate the minimum stopping distance in meters.
First we transform the initial speed of to , then we will analyze the acceleration as it slows down when the driver indicates that he steps on the brakes, ie, have a negative acceleration that is in and needs to be transformed in by will be the same as .
