A heavy ball with a weight of 150 N is hung from the ceiling of a lecture hall on a 4.1-m-long rope. The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.5 m/s as it passes through the lowest point. What is the tension in the rope at that point?

The tension in the rope is 262.88 N

Explanation:

Given:

Weight N

Length of rope m

Initial speed of ball

For finding the tension in the rope,

First find the mass of rod,

                         ( )

  kg

Tension in the rope is,

  N

Therefore, the tension in the rope is 262.88 N

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
