A watermelon is dropped from the edge of the roof of a build- ing and falls to the ground. You are standing on the pavement and see the watermelon falling when it is 30.0 m above the ground. Then 1.50 s after you first spot it, the watermelon lands at your feet. What is the height of the building? Neglect air resistance.

Pls answer #24 with complete solutions, thanks! Analyze the problems carefully, then solve them. Be systematic when answering. Write the given, label them; the required; and all calculations pertinent to the problem. Express your numerical answers with the appropriate number of significant figures.
1 / 1|. 100% +| E - Paper Homework (counts as Reading Assignment) Рар Solve the following two problems, showing all work and expressing your answer in the proper units. You do not need to use the rules for significant digits, but the precision of your answer should be comparable to the precision of the quantities given. 1. Note: Koalas tend to fall out of trees. Their skulls have properties that tend to protect them from concussions and other damage, so we can be happy about that. A koala falls 2.6 m from a tree. Calculate its velocity just before hitting the ground (unharmed). Use the sign of the velocity to indicate direction (up or down).

Please provide a clear and complete solution. Answer fast for I have 30 minutes left. Thank you very much.
Please try not to use derivatives or integrals to calculate stuff. Thank you.
Just wanted to check if my answers are correct :) please let me know if I’ve made any mistakes.
For this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?
Illustrate and solve the following problems. Show the complete solution (in GRESA format), always include the SI units on your solution, express your answer in two decimal places and box your final answer.
