Answer: No
Explanation:
The force F required is equal to the Force exerted in stretching the first material since conditions are the same
When the velocity of an object changes, it is acted upon by a force
You get the net force acting on it ... the sum of the strengths and directions
of all the individual forces there may be.
Answer:
<h2>4.6 m/s²</h2>
Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula
<h3>

</h3>
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
Since the body is from rest u = 0
From the question we have

We have the final answer as
<h3>4.6 m/s²</h3>
Hope this helps you
