Answer:
18.6 m/s
Explanation:
= Initial height of the balloon = 11 m
= initial speed of the ball
= initial vertical speed of the ball = 7 m/s
= initial horizontal speed of the ball = 9 m/s
initial speed of the ball is given as
= final speed of the ball as it strikes the ground
= mass of the ball
Using conservation of energy
Final kinetic energy before striking the ground = Initial potential energy + Initial kinetic energy
The answer is A for this one
Answer: This book is about a mom that is always saying no to her kids and is always pushing them to focus on what they are doing, but one day the mom or dad runs into a man that does what he calls "A Yes Day" with his kids and what this is, is for 24 hours you say yes to whatever you want to do and you aren't able to say no. So the mom tries yes day with her kids and they go through many crazy/extreme events. This has to deal with hygiene because the kids trash the house and get very dirty in a few parts of the movie. They always try to be as clean as possible, but the limits have been broken... This is why I think this movie has to deal with hygiene.
