two forces are shown acting on a body below. calculate the equilibrant force on the body and state what effect it will have on the situation. (n = newton in the diagram)
a block with crate written on it placed perpendicularly on a line. two arrows are coming out of it, with one arrow pointing one way labeled as one hundred and fifty n west and second arrow pointing the other way labeled as two hundred and fifty n east

a. 100 n west, the body will not move

b. 400 n west, the body will move to the west

c. 100 n east, the body will move to the east

d. 400 n east, the body will not move

I'd say C.

Explanation:

When doing problems like this, with two forces opposite each other, its good to think of the lines as people pulling in the direction of the arrow. The larger arrow is just a "stronger" person pulling in their direction. We can see that the larger force - given in Newtons (N) - is about 100 Newtons stronger in the East direction. How do we know? Just by looking at the diagram, and subtracting the forces; 250 N -150 N = 100 N. Combining that means, the crate will likely move to the east with 100 N.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
