A force of 30 newtons and a force of 20 newtons act concurrently on an object. Which of the following
resultant forces could be produced using these two
forces?

The resultant force produced by the two concurrent forces is 50 N.

The given parameters;

Concurrent forces, are forces acting at a point and the resultant of such forces is a single force when acting alone will balance the effect of the concurrent forces.

where;

Thus, the resultant force produced by the two concurrent forces is 50 N.

(2): 25 N.

Explanation:

We know that two forces act concurrently on the same object.

One force has a magnitude of 30 N, so the first force can be written as:

F = (fx, fy) such that:

30N = √(fx^2  + fy^2)

And other force of 20 N, let's call it G.

G = (gx, gy)

Such that:

20 N = √(gx^2 + gy^2)

Now, the maximum possible resultant force is when both forces point in the same direction.

Then we can directly add them; G + F = 20N + 30N = 50N

And the minimum resultant force is when both forces point in opposite directions, then we can directly subtract: F - G = 30N - 20N = 10N.

Then the resultant force, F', will be:

10N ≤ F' ≤ 50N.

The only option in that range is the second option, (2) 25N.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
