Answer to Problem 40P
Solution:
The speed at point
The speed at point
The speed at point
Explanation of Solution
Given info:
Formula used:
The summation of potential and kinetic energy at any point is constant.
Kinetic energy of an object can be obtained by:
Gravitational potential energy of an object can be obtained by:
Where, m is the mass, g is the gravitational acceleration and h is the height.
Calculation:
Energy at point
Let speed at point
Let speed at point
Conclusion: The summation of potential and kinetic energy at any point is constant.
The speed at point
The speed at point
The speed at point
