Answer:
Explanation:
The interrelationship between the distance covered by a body, the initial velocity of the body, and the time taken by the moving body during its motion is given by the second equation of motion.
The second equation of motion is given as follows:
where,
s = the distance covered by the body
vi = initial velocity of the body
t = time taken by the body during motion
a = acceleration of the body
Okay this might be the hardest one of all um I think it is 99
Newton's second law is the hardest to describe as it is about momentum (F = ma), and a lot of people don't know the concept of momentum.
Newton's first law of motion:- every object moves in a straight line unless acted upon by a force.
Newton's 2nd law of motion:-the acceleration of an object is directly proportional to the net force exerted and inversely proportional to the item's mass. Newton's 2nd law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
Newton's 3rd law of motion:- For every action, there's an equal and opposite reaction.

Answer: 2Mg/k
Explanation:
Let a be the extension experienced by the spring when a mass M is released from rest. And k is the force constant value
The potential energy lost by the mass is equal to that gained by the spring.
The potential energy lost by the mass = M x g x a
The energy gained by the spring = 1/2 x K x a^2
Therefore, M x g x a = 1/2 x K x a^2
Mga = Ka^2/2
2Mga = ka^2
Making a the subject of the formula,
Dividing through by a,
2Mg = ka
Therefore, a = 2Mg/k
The maximum extension produced in the length of the spring will be 2Mg/k.
