The amount of force required to stretch or compress the spring is known as the spring force. Its unit is Newton(N). Force is needed to stretch spring is 10.2 N.
<h3>What is spring force?</h3>
The force required to extend or compress a spring by some distance scales linearly with respect to that distance is known as the spring force. Its formula is
F = kx
The given data in the problem is;
F is the spring force =?
K is the spring constant= 8.5 N/m
x is the length by which spring got stretched = 1.2m
Hence the force is needed to stretch the spring is 10.2 N.

Answer:
See the answers below.
Explanation:
The magnitude can be easily found by means of the Pythagorean theorem.
We know that the coordinates in x and in y are negative, therefore the vector should be located in the fourth quadrant, see attached image.
And the angle with respect to the horizontal can be determined by means of the tangent of the angle.
These are 40 degrees below the X-positive horizontal axis.
Answer:
Explanation:
From the question we are told that:
Height
Time
Generally the Newton's equation for Initial velocity upward is mathematically given by
Generally the velocity at elevation and depression occurs as ball arrives and passes through S=28
Generally the Newton's equation for time to reach initial velocity is mathematically given by
Answer:
1.12 N
Explanation:
Let the masses be m and M and distance be d . Force between them is .28 N .
Applying Newton's law of Gravitation
.28 = G x m M / d²
distance is halved , so distance becomes d /2
Force of attraction = G m M / ( d/2)²
= 4 Gm M / d²
= 4 x .28
= 1.12 N .
