# What is your acceleration towards the end of the cliff?

• mat331760298
In summary, the conversation discusses a scenario where a person weighing 100kg is holding onto one end of an ideal vine while their friend, weighing 50kg, is hanging onto the other end above a pack of Velociraptors. The vine is affected by a sudden sleet storm, causing all friction to be removed. The question is what the acceleration of the person weighing 100kg will be towards the end of the cliff. The conversation also mentions the use of Newton's second law (Fnet=ma) and drawing free body diagrams to determine the forces acting on each person. However, the speaker had difficulties solving the problem and determining the force of tension in the vine.

1.
You having a mass of 100kg hold one end of an ideal vine (infinitely strong, completely flexible, but having zero mass). The vine runs horizontally to the edge of a cliff, then vertically to where your friend (mass 50kg) is hanging on, above a pack of hungry Velociraptors. A sudden sleet storm has removed all friction, assuming that you can hang on, what is your acceleration towards the end of the cliff?

2.
Fnet=ma
Fnet1=Fg1 - Ft
Fnet2=Fg2 - Fn + Ft

3. I drew the picture and tried to rearrange equations and use substitution, but had troubles and can't get a reasonable answer. i know 100kg person has Fg2 of 980N down and Fn of 980N up. the 50kg person has a Fg1 of 490N down, but i can't get the Force of tension in the rope (Ft)

Draw free body diagrams of each person and note the forces acting on each. You have identified correctly the forces on the 50 kg person (his weight down, and unknown tension force up), which is the net force, and which must be equal to 50a.
For the other person, you need not look in the vertical direction, just consider the forces acting on her in the x direction.. What are they? Then use Newton 2 for that person also. Then continue...

## 1. What is acceleration?

Acceleration is a physical quantity that measures the rate of change of an object's velocity over time. It is a vector quantity, meaning it has both magnitude and direction.

## 2. How is acceleration calculated?

Acceleration can be calculated using the equation a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.

## 3. What is the difference between acceleration and velocity?

Velocity is the rate of change of an object's displacement over time, while acceleration is the rate of change of an object's velocity over time. In other words, velocity tells us how fast an object is moving, while acceleration tells us how quickly an object's velocity is changing.

## 4. How does acceleration affect motion?

Acceleration affects motion by changing the speed or direction of an object. When an object is accelerating, its velocity is constantly changing, meaning it is either speeding up, slowing down, or changing direction.

## 5. How does acceleration towards the end of a cliff differ from acceleration towards the beginning?

Acceleration towards the end of a cliff may differ from acceleration towards the beginning because it may be influenced by external factors such as air resistance or the slope of the cliff. Additionally, the velocity and position of the object at the beginning and end of the cliff may also affect the acceleration.
