Answer:
a truck mass 2000. kg is travelling at 45 m/s when the driver spots a policeman ahead. The driver applies the brakes lightly for 3.0 s until he slows down below the speed limit. If the average force applied to the brakes was 1.4 x 10^4 N, by how much did the kinetic energy of the car change?
Step-by-step explanation:
Five times 12 is 60 and Six times five us 30 add them up you get 90 dollar when you work 17 hours between to Jobs
Answer:
the value of "b" is 8.9 so b=8.9
Answer:
8.4 kg
Step-by-step explanation:
First, find how much waste is created in a week:
Multiply 2 by 7, since they create 2 kg of waste each day:
2(7)
= 14 kg
Then, find 60% of this:
Multiply 14 by 0.6:
14(0.6)
= 8.4
So, the amount of compostable waste created by 1 person in a week is approximately 8.4 kg
For the 2nd part of 2. just plug in what you have for G in your previous graph into the equation. This will give you H for all 5 columns . Like 3×8(-1+5)= h = 3× 32= 96 so H should equal 96 and so on as far as this function.
For number 3. The equation is given so just plug in your T for time which is 3 seconds, so...-16(3)^2+90(3) = H the height at 3 seconds. I'm doing it in my head but should be the height is 414. You should also say whether it's ft or inches etc because the teacher or yourself left that out of the equation which is also vital lol.
