A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
The last statement is the correct one.
-- The net force on the box is 2N to the left.
-- The box will move to the left and accelerate to the left.
-- F=ma . a=F/m . a=(2N)/(4kg).
a = 0.5 m/s^2 to the left.
160 I think or 200
the lines are pulling on the same side so you add those
A) -12 + 10
B) More force is acted on in that direction
C) Net force/Mass (-2/4)
net force = 2N
direction = left
acceleration = 0.5 meters/second
the net force on an object is the sum of all the forces acting on it
since Bob and John pull in opposite directions, we subtract forces and the net force is
12N - 10N = 2N
since there is a greater force to the left (12N), the box moves to the left
use the formula Force = acceleration * mass to find acceleration
Force = 2N
mass = 4 kg
Force = acceleration * mass
acceleration = Force / mass = 2 / 4 = 0.5 meters/second
The net force on the box is 2 N to the left.
The box will move to the left.
The acceleration on the box is 0.5 m/s^2 to the left.
Let's say movement to the right is positive and left is negative.
Bob: +10 N
John: -12 N
Add those together and you get a net force of -2 N, and the negative sign means that the box is moving to the left.
For the acceleration:
Fnet = ma
-2 = (4 kg)a
a = -0.5 m/s^2
Again, the negative sign in this answer means the box is being accelerated to the left.
