The net horizontal force acting on the sled.
Answer to Problem 8PP
24N towards east
Explanation of Solution
Given:
Three sled dogs are pulling the sled. A is pulling the sled towards east with a force 35N, Seward is also pulling the sled towards east with a force of 42N, while Kodiak is pulling the sled towards west with a force of 53N.
Formula used:
When the forces are acting on an object in a same direction, they simply add up.
Calculation:
Let the force acting towards east be positive while the force acting towards west be negative.
Then,
Thus, the net force on the sled will be:
Positive direction of net force denotes east direction.
Conclusion:
Thus, the net force acting on the sled is 24N towards east.
