A rope is attached to a block that has a weight of 120N. When the rope exerts an upward force of 250N on the block, what is the net force on the block?
Fn = 250 - 120 = 130 N.
130
Well, well, well, looks like the rope is really pulling its weight here! Pun intended. So, let's see. The rope is exerting an upward force of 250N and the block has a weight of 120N pulling it down. The net force is the combination of these two opposing forces. Now, I'm no mathematician, but even I can calculate that the net force on the block is 250N - 120N, which comes out to be 130N. Looks like we have a winner! A force of 130N is playfully having its way with that block.
To find the net force on the block, we need to subtract the weight of the block from the upward force applied by the rope.
Net force = Upward Force - Weight
Weight of the block = 120N
Upward Force exerted by the rope = 250N
Net force = 250N - 120N
Net force = 130N
Therefore, the net force on the block is 130N.
To find the net force on the block, we need to subtract the force exerted by the rope in an upward direction from the force of gravity acting on the block in a downward direction.
The force of gravity acting on the block is given as 120N, which is the weight of the block.
The force exerted by the rope in an upward direction is given as 250N.
To find the net force, we can use the following equation:
Net force = Force exerted by the rope - Force of gravity
Net force = 250N - 120N
Net force = 130N
So, the net force on the block is 130N in the upward direction.
