Answer:
8m
Explanation:
The magnitude m of a vector (x, y) is given by
m = -------------------------(i)
where;
x and y are the x- and y- components of the vector.
From the question;
m = 10m
x = 6m
Substitute these values into equation (i) as follows;
10 =
Solve for y;
<em>Find the square of both sides</em>
10² = 6² + y²
100 = 36 + y²
y² = 100 - 36
y² = 64
y = √64
y = 8
Therefore, the y-component of the position vector is 8m
Force = mass times acceleration
F = 21000 x 36.9 = 774900
Therefore, 774900N force is required.
Answer:
Pushes and pulls refer to the force that attracts or repels certain other materials without actually touching them.
Explanation:
Pushes and pulls are the forces exerted by the magnet on certain materials around it without, actually touching them. This push and pull is exerted through a region around the magnet called its magnetic field. The strength of this push and pull force is determined by, the strength of the magnetic field. A strong push or pull force is exerted by a strong magnetic field, and in turn a strong magnet and, a weak push and pull force is exerted by a weak magnetic field and, in turn a weak magnet. A push force is a repulsion while a pull force is an attraction. When a magnetic object is in the region of the magnetic field, it either attracts or is repelled away from the source of the magnetic field.
The x and y coordinates of the particle at this moment is (6x + 4.5y) m.

Position of the particle </h3>
The position of the particle at any instant is determined from the velocity and acceleration of the particle as shown below.
v² = u² + 2as
where;
- v is the final velocity of the particle
- u is the initial velocity
- a is the acceleration of the particle
- s is the position of the particle
v² = 0 + 2as
v² = 2as
s = v²/2a
<h3>X and y - coordinates of the particle</h3>
Thus, the x and y coordinates of the particle at this moment is (6x + 4.5y) m.
