Answer: The acelaration is 2 m/s^2
Explanation: Using the second Newton law
The total force acting over the object is equal to the mass x accelaration, that is:
We considerer the applied force to the object equal to 25N
and the friction force of 15 N
25N-15N= m*a
Answer:
The value is
Explanation:
From the question we are told that
The amount of power delivered is 
The time taken is 
The wavelength is 
Generally the energy delivered is mathematically represented as

Where
is the Planck's constant with value 
c is the speed of light with value 
So

=> 
The lists from greatest to lowest change in velocity.Dustin → Diego → Kira. Option A is correct.
<h3 /><h3>What is acceleration?</h3>
The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The acceleration is obtained one by one from the given data as the ratio of the velocity to the time.
For the acceleration of each, you can refer to the excel table attached below.
The velocity changes are listed from largest to least. Dustin and Diego Kira.
Hence, option A is the right answer.
