Answer:
F = 0.483 N
Explanation:
Initial momentum,
Final momentum,
Time, t = 31 s
We need to find the force of a lead ball. We can use here the impulse momentum theorem.
F is force
So, the force is 0.483 N.
A monkey hangs motionless by one arm from a tree branch. Draw the free-body diagram.
1 answer:
Find the free-body diagram in attachment.
Explanation:
The free-body diagram of an object is a diagram representing all the forces acting on a body. Every force is represented using an arrow, where:
- The length of the arrow is proportional to the magnitude of the force
- The direction of the arrow shows the direction of the force
For the monkey in this problem, we have two forces acting on it:
- The weight of the monkey, labelled as (mg), acting downward, where
m is the mass of the monkey
g is the acceleration of gravity
- The tension in the tree branch, labelled as T, which acts upward
The monkey is motionless: this means that its acceleration is zero, so the net force actin on it is zero - this means that the forces acting on the monkey, the weight and the tension, are balanced, therefore they are shown as two arrows of same length, but opposite direction.
