Kinetic Energy= 1/2 x mass x velocity^2
600 = 1/2 x 8 x velocity^2
(Divide 600 by 1/2 and 8)
600/(1/2) = 8 x velocity^2
1200/8 = velocity^2
150 = velocity^2
(Square toot both sides)
12 m/s = velocity
Answer:
no poop comes out from your but
Explanation:
Answer:
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The mass of the wagon is 12 kilograms and the acceleration is 3 meters per square second.
Substitute the values into the formula.
Multiply.
- 1 kilogram meter per square second ( 1 kg*m/s²) is equal to 1 Newton (N)
- Our answer of 36 kg*m/s² is equal to 36 N
The force required for the 12 kilogram wagon to accelerate at 3 meters per square second is <u>36 Newtons.</u>
Answer:
1.35 miles
Explanation:
Since the slope is 14% grade = -14/100. This is a negative slope.
The distance of 1000 ft descended is a vertical descent, so assuming our initial position is 0, and Δx is the change in horizontal distance.
tanθ = -14/100 = (0 - 1000)/Δx = - 1000)/Δx
-14/100 = - 1000)/Δx
Δx = -1000 × -100/14= 7142.86 ft
5280 ft = 1 mile
7142.86 ft = 7142.86/5280 miles = 1.353 miles ≅ 1.35 miles
The current is defined as the ratio between the charge Q flowing through a certain point of a wire and the time interval,
:
First we need to find the net charge flowing at a certain point of the wire in one second,
. Using I=0.92 A and re-arranging the previous equation, we find
Now we know that each electron carries a charge of
, so if we divide the charge Q flowing in the wire by the charge of one electron, we find the number of electron flowing in one second:
