Answer:
To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. or v2 = u2 + 2as and this equation of motion can be used to find the final velocity or the distance travelled if the other values are given.
Explanation:
v= u + at
s =( u + v ) t /2
s = ut + at2/2
v2 = u2 + 2as
"Edmond Locard" states that there is an exchange of materials when two objects come into contact with each other.
<u>Explanation:</u>
A French criminologist who was popular as the "Sherlock Holmes of France," the pioneer in forensic science named as Dr. Edmond Locard. He articulated forensic science's fundamental principle "Each touch leaves a trace." This became known as Locard's philosophy of exchange. A Locard hypothesized that each and every time you touch another person, place or object, the result would be an exchange of materials. Burglars, for instance, will leave evidence of their existence behind and take traces with them too.
Answer:

Explanation:
Given that

We know that acceleration a given as




We know that



So the magnitude of force F

Answer:
40,000
Explanation:
Momentum is defined as mass*velocity, so a doubling of velocity means a doubling of momentum
