Answer:
5.61s
Explanation:
And we need to find out the time taken by the ball to reach the ground .
- The initial velocity of the ball will be 0 since it is dropped .
Here we can use the First equation of motion , namely ;
where the symbols have their usual meaning . Now substituting the respective values , we have,
Explanation:
The given data is as follows.
mass = 227.8 kg, volume = 0.1189
It is known that formula for volume of a sphere is and density is as follows.
Density = ........ (1)
=
= 1915.895
Hence, putting the given values into equation (1) as follows.
Density =
1915.895 =
= 227.8
r = 0.305
Thus, we can conclude that radius of the sphere is 0.305 .
the median is 1 because it is in the middle
