Answer: PE = 800j, KE = 800J
Explanation:
To calculate the potential energy, we use the formula
Potential Energy = Mgh
M = 20kg, g = 10m/sˆ2 , h = 4m
=20 × 10 × 4
=800J
At the maximum height S = 4 and the initial velocity u = 0 The acceleration g = 10m/sˆ2
Using the third equation of motion
vˆ2 = uˆ2 + 2as
= 0ˆ2 + 2 × 10 × 4
vˆ2 = 80
Kinetic Energy (KE) is given by
KE = ½ mvˆ2
= ½ × 20 × 80
=800J
Political ideology is an established set of thoughts, principles, doctrines, among other things of some group or movement to explain the way society should be in order to achieve social order. This term can be applied to political culture, which has to do with the shared beliefs and values related to government and politics that are developed over a period of time in a community. When discussing political culture, political ideology has a tendency to refer to the influence of political philosophies that have had a deep, broad influence on a particular community. Thus, a political point of view shared by many people can be adopted and even modified by a particular community.
