Answer:
Explanation:
By energy conservation and work energy theorem we can say that after bullet hits the block, it will move on the rough floor and comes to rest
so here work done by frictional force = change in kinetic energy
so we know that
now by momentum conservation we have
<h3><u>Answer;</u> </h3>
= 0.03066 m
<h3><u>Explanation;</u></h3>
Work done or energy by a spring or an elastic material is given by the formula;
Potential energy = 1/2 kx²
Where, k is the spring constant and x is the distance stretched.
Therefore;
47 J = 1/2 (100000 n/m) x²
47 J = 50, 000 x²
x² = 47 /50,000
x² = 0.00094
x = 0.03066 m
Therefore,<u> x = 0.03066 m </u>
Answer:
when new information disproving the current theory becomes available.
Explanation:
hope this helps..
This should include distances. Displacement is the shortest distance from point A to point B. Distance is the total length of travel. For an example I have included a simple map.
Displacement would not be an accurate representation of the driving instructions because it would not tell the total length of travel. Basically, the driver would be going through buildings if you told them displacement. Directions would tell them the roads traveled.
