It means cork has less density comparing to water
Use the formula for distance dropped from rest:
D = 1/2 a t^2 .
With no air resistance, you get about 8.8 sec.
I'm pretty sure you can fill in the missing work.
Answer:
Explanation:
The sense of weightlessness in orbiting satellite is because of the lack of any contact-forces. ... Thus, both the astronaut and the satellite have the same value of g, which is again equal to the centripetal acceleration of the satellite. These two neutralize each other, causing everything to appear weightless.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Below is the solution:
acceleration a = g(sinΘ - µcosΘ) = 9.8m/s² * (sin30º - 0.1*cos30º) = 4 m/s²
<span>velocity v = a*t = 4m/s² * 6.4s = 26 m/s </span>
