Explanation:
In this case, when the collar mass is released, it will move from the rest point, to a point between A and B and then to point C. While it approaches point C, the amount of stretch will decrease and the spring force will reduce.At point C, the spring reaches its maximum stretch, leaving un-stretched length of spring l, making point C the position where the velocity of the collar is maximum.The energy possessed due to motion of the collar is kinetic energy, thus the magnitude of the velocity can be calculated from;
Kinetic energy, K.E = 1/2*m*v²
Thus
where m is mass of collar and v is speed of collar. The faster the collar the more the kinetic energy.

The purpose of a block to add a value to the end of an array.
<h3>What is the function that adds an element to the end of an array?</h3>
The push() is known to be often used to add an element to the end of your array.
The end() function is known to be one that transmit the internal pointer to, and also the outputs, the last factor in the array.
A null or zero value is known to be that which marks the end of an array and it is said to be the very equivalent of the null char for any kind of string
Hence, in the above scenario, The purpose of a block to add a value to the end of an array.
Therefore, option D is correct.

Answer:
500 N
Explanation:
Given;
Mass of the car, M = 1000 kg
initial speed of the car, u = 0 m/s
Final speed of the car, v = 60 m/s
Time, t = 1 min = 60 s
Now,
Force, F is given as:
F = Ma
where,
a is the acceleration
From the Newton's equation of motion, we have
v = u + at
on substituting the values, we get
60 = 0 + a × 60
or
a = 1 m/s²
Thus,
Force = 1000 × 1 = 1000 N
now,
this force will be equal to the friction force provided by the rear wheels
let the friction force on a single rear wheel be 'f'
thus,
2f = 1000 N
or
f = 500 N
Answer:
Larger
Explanation:
When a vehicle is accelerated, the weight of the vehicle and the driver is transferred to the front of the rear of the car.
This transferred weight is nothing but the additional weight that presses the car's suspension in the downward direction thereby affecting tire contact patch in the rear due to which the rear tires loses adhesion.
