Just assume that the sun has the average mass of all the stars
Then divide the mass of the galaxy by the mass of the sun.
<span>10^30 has 30 zeroes after it. 10^42 has 42 zeroes.
The answer would have 12 zeroes which concludes a trillion stars. </span>

Answer:
Initial velocity = 39.2m/s
Maximum height is 78.4m
Explanation:
Given

Solving (a): Initial Velocity
Using first law of motion:

Where


<em />
<em> [g represents acceleration due to gravity]</em>

Substitute these value in the above formula:



Take g as 9.8m/s²


<em>Hence, initial velocity = 39.2m/s</em>
Solving (b): Maximum Height
This will be solved using second equation of motion

This becomes

Substitute values for u, t and g



<em>Hence, the maximum height is 78.4m</em>
