Answer:
u =0.269
Explanation:
To find the coefficient of friction we know the following formula
Where
= Force of Friction
= Coefficient of Friction
= Normal Force
Thus we first find the Normal force (N). Remember that the Normal force is perpendicular to the surface, and is equal to the opposing component of Weight (W). Since the surface here is horizontal, then the Normal force will be equal to the Weight.
Now we find the Force on the spring that caused the extension of 3.25cm or 0.0325m
Where
= Force of Friction
= Force Constant
= extension
Hence
Now to find the coefficient of friction we use the first formula
Answer:
a) No
b) No
Explanation:
When a bat is hit in a game of baseball such that it flies out of the field that means it is going with some angle to the horizontal.
a)
Then is such a case the velocity of the ball is never parallel to the acceleration because there acts a net acceleration which is resultant of the acceleration due to the applied force and the acceleration due to gravity but a component of the velocity when the ball descends the height acts parallel to the gravity.
b)
At no point during the motion of the ball its velocity is perpendicular to its acceleration because it has an initial angle of projection form the horizontal.
""A series of activities that have proven to be effective in successfully implementing safe"" This statement defines the safe Implementation roadmap.
<h3>What is safe implementation roadmap ?</h3>
The Safe Implementation Roadmap outlines the stages," that an organization may take to execute safe in a systematic, dependable, and effective manner.
While the implementation of safe may vary depending on the situation, the Implementation roadmap provides insight into a fairly prevalent pattern.
The safe implementation roadmap is made up of an overview graphic and a 12-article series that detail a strategy and a sequence of actions that have been proved to be successful in implementing Safe.
Hence,the given statement defines the safe Implementation roadmap.
