The spring is now compressed so that the unconstrained end moves from x=0 to x=L. Using the work integral W=∫xfxiF⃗ (x⃗ )⋅dx⃗ ,
find the work done by the spring as it is compressed. Express the work done by the spring in terms of k and L?
1 answer:
solution:
the spring force exerted by spring with spring constant k is given by
where k is spring constant
and x is deformation of spring
in order to calculate word done by the spring
the work done by the spring as it is compressed from x=0 to x=L
inserting the limits x=0 and x=L
we get work done in terms of k and L

Explanation:
The work done by a force in moving an object is given by
(1)
where
F is the magnitude of the force
d is the distance covered by the object
is the angle between the direction of the force and the motion of the object
In this problem, the force applied to the object is
F = 3.0 N
This force is always tangential to the track: this means that at every instant, the force is parallel to the motion of the object, so
And the distance covered is equal to the circumference of the circle, which is:
where r = 2.5 m is the radius.
Now we can substitute into eq.(1) to find the work done:

Answer:
<em>When a moving car brakes to a stop the </em><em>kinetic energy of the car is converted to heat energy. </em>
Explanation:
A moving car has kinetic energy.
It is given by the equation
Where m denotes mass of the car and v denote sits velocity. When the brakes are applied the velocity becomes zero and the car doesn’t possess kinetic energy anymore.
According to law of conservation of energy can neither be created nor be destroyed but can only be transformed from one form to another. On coming to a stop, the kinetic energy of the car gets converted to heat. The friction between the tyre and the road heats up the tyre.
