I think so yes, it makes sense
Answer: Minimum speed needed by the Olympic champion at launch if he was traveling at 6.8 m/s at the top of the arc is 11.65 m/s.
Explanation:
Velocity is only in horizontal direction at the top most point which is similar to the velocity in the horizontal direction at the time of launch.
Now, according to the law of conservation of energy the formula used is as follows.
As speed at which the person is travelling was 6.8 m/s. Hence, the initial velocity will be calculated as follows.
Thus, we can conclude that minimum speed needed by the Olympic champion at launch if he was traveling at 6.8 m/s at the top of the arc is 11.65 m/s.
2 minutes is 120 seconds, so if you were finding vibrations per minute, it would be 60 times a minute.
Answer:
variable
Explanation:
Globular clusters is defined as collection of numerous star that revolve around the galaxy core. they are so bound to each other that they formed spherical shape. This boundness among the star is due to gravity. The main characteristics of globular cluster is that they contain high density of star at center.
Every galaxy consist of various number of globular cluster and even milky way consist of 125 to 200 cluster
