I an looking for the answers as soon as possible
6. A rock is moving in outer space at 11 m/s. A gust of interstellar space wind comes along and pushes on the rock for 7
Seconds, giving the rock a final velocity of 38 m/s. What was the rocks acceleration?
7. A rocks starts to roll down a hill. The rocks acceleration down the hill is 3 m/s/s, and it starts from rest. How long does it
Take the rock to reach a speed of 66 m/s?
8. How many years are there in one Exa-second?
9. A rock is thrown down a well at 40 m/s. If the rock falls for 300 seconds before hitting the water, how deep is the well?
10. If the same rock is dropped from rest down the same well, how long does it take the rock to hit the water?
11. A car goes from a position of 2 m to 14 m in 2.4 s. If the car started from rest, what was the cars acceleration?
12. A bird suddenly dies and falls from the sky. If the dead bird falls 232 m in 18 seconds, what was the birds original vertical
Velocity? (vertical because gravity ONLY acts vertical)
13. How many years in a femto-second?
14. If a rock is thrown upward at 213 m/s, what speed will the rock have at the top of its path?
15. How long does it take a rock to get to the top if it leaves your hand traveling at 74 m/s?
16. If it takes a rock 8.7 seconds to get to the top after being thrown upward, how long will it take to fall back down to the
Starting position?
17. If a rock takes 3.4 seconds to reach the bottom after it reaches the top, how far did it travel upward?
18. How high does a rock go if thrown upward at 33 m/s?
19. How much speed does a truck gain each second if it travels at 89 cm/year/s?
20. What is the slope on a velocity/time graph? Distance/time graph?
PLEASE SHOW ALL THE WORK THANKS
If you could write the numder next to the one you answer I will appreciate it
Thank you
