<span>122 g * 4,186 (j/g*°c) * 23°c = 11745.916 j </span>
both it velocity and acceleration is zero.
Answer:
Hi there!
There are many possible answers!
My best guesses are:
1) Knowing how they work will prevent injury! For example, knowing that the gears twist will stop you from putting your finger in it!
2) Allowing you to use it! Knowing how to line up the edge of the can with the tool will let you use it properly!
Hope this helps
Answer:
The initial velocity is 12.34[m/s]
Explanation:
To understand this problem, let's draw a sketch of what is happening. In the attached image we can fin de sketch.
According to the equations of uniform movement accelerated we have to express them in the two components x and y.
In this problem we will analyze first the movement in the y axis and its equation to obtain the velocity in the initial point (o) and then with the angle of 33° respect to the horizontal we can find the main velocity.
In the previous equation we have the negative term - (2*a*y), the reason for the negative sign is because gravity is the acceleration that is acting downwards.
Therefore:
Now with the velocity in the y component, we can calculate the main vector of the velocity.
The main topic to understand in this problem is that when the height is maximum the velocity will be zero in the y component, therefore Vy=0 and we can simplify the problem.
