Answer:
The angle is 23.2 radians, equivalent to 3.69 revolutions.
Explanation:
First, we need to find the angular acceleration of the wheel. This can be done using one of the kinematic formulas:
Since the final angular velocity is zero after 5.5 revolutions (equivalent to 11π radians) we have that:
Now, using the same equation, we can solve for the requested angle:
Finally, it means that the angle through which the wheel has turned when the angular speed reaches 1.80 rad/s is 23.2 radians, equivalent to 3.69 revolutions.
<h2>Answer:53.63
</h2>
Explanation:
The equations of motion used in this question is
When a object is projected horizontally from a sufficiently height,the x-component of acceleration remains zero because there is no force that drags the object in x direction.
But,due to gravity,the object accelerates downward at a rate of .
In X-Direction,
Given that initial velocity==
Using ,
In Y-Direction,
Given that initial velocity==
Using ,
