Answer:
The speed of the ball is 9.07 m/s.
Explanation:
Given that,
Mass of the lead ball, m = 55 kg
Height of the tower, h = 55 m
We need to find the speed of the ball it has traveled 4.20 m downward, x = 4.2 meters
The initial speed of the ball will be 0 as it was at rest initially. Let v is the speed of the ball after it has traveled 4.20 m downward. It is a case of equation of motion such that :
Here, a = g
v = 9.07 m/s
So, the speed of the ball is 9.07 m/s. Therefore, this is the required solution of given condition.
The historical method includes what steps?
The average daily annual temperature range is exceeded in places such as deserts. Deserts tend to be hotter due to the lack of water contained within them. This means that all of the sun's thermal radiation heats up the ground and air. These factors cause deserts to have above average temperatures.
Answer: Participating in all of the above can improve flexibility.
Explanation:
A practice that helps in improving or developing inherent power in order to bring peace and harmony to the body of a person is called yoga.
Yoga includes different postures that also help in providing flexibility to the body.
Pilates is another method of providing muscular strength and low impact flexibility to a human body.
Swimming also a good exercise that provides flexibility.
Thus, we can conclude that participating in all of the above can improve flexibility.
