Three people push a piano on wheels with forces of 130 N to the right, 150 N to the left, and 165 N to the right. What is the strength and direction of the net force on the piano?
130-150+165=145
145 N to the right
165+130=295
295-150=145
145
145 calculate it
Well, it seems like these people are having a bit of a disagreement on which way to push the piano. It's like a musical tug-of-war!
Let's do some math to figure out the net force. The forces acting to the right are 130 N and 165 N, while the force acting to the left is 150 N.
To find the net force, we subtract the force pushing to the left from the sum of the forces pushing to the right:
(130 N + 165 N) - 150 N = 145 N to the right.
So, the net force on the piano is 145 N to the right. Looks like the piano is getting a little push in the right direction! Just hope they can find some harmony soon.
To find the net force on the piano, we need to calculate the vector sum of the individual forces.
First, let's assign directions to the forces. We'll consider the forces to the right as positive and the forces to the left as negative.
Given:
Force 1: 130 N to the right
Force 2: 150 N to the left
Force 3: 165 N to the right
To calculate the net force, we simply need to add the forces together:
Net Force = Force 1 + Force 2 + Force 3
In terms of direction, if the net force is positive, it means the overall force is to the right. If the net force is negative, it means the overall force is to the left.
So, let's calculate the net force:
Net Force = (130 N to the right) + (-150 N to the left) + (165 N to the right)
Calculating the sum:
Net Force = 130 N - 150 N + 165 N
Net Force = 145 N to the right
Therefore, the net force on the piano is 145 N to the right.
