Correct answer is:
<span>B. Subtract the initial velocity from the final velocity and divide the result by the time
In fact, the formula to calculate the acceleration is
</span>
<span>where vf is the final velocity, vi the initial velocity, and t the time.</span>
Answer:
a
b
Explanation:
From the question we are told that
The spring constant is
The mass of the block is
Considering question a
Generally the weight of the block is mathematically represented as
=>
=>
Generally the force exerted on the spring is mathematically represented as
At equilibrium
=>
=>
=>
Considering question b
Generally the energy stored in the spring is mathematically represented as
Now the potential energy of the block before it is drooped is mathematically represented as
Generally from the law of energy conservation we have that
=>
=>
=>
How are we suppose to answer this tho?
Answer:
thankkkkkksssssssssssssss
