Answer:
64 m
Explanation:
Using the following symbols
x: distance
v: velocity
a: constant acceleration
t: time
v₀: initial velocity
x₀: initial position
The equations of motion for a constant acceleration are given by:
(1) x = 0.5at²+v₀t+x₀
(2) v = at+v₀
From equation (2) you can calculate the time t it takes the car to come to a complete stop.
(3) t = (v-v₀)/a
Now you plug equation (3) in equation(1):
(4) x = 0.5a((v-v₀)/a)²+v₀((v-v₀)/a)+x₀
In equation (4) the position x is the only unknown.
You would have to use a machine to convert the colors to one visible by humans or become some other species of animal with a larger light spectrum.
Answer:
benefits
Diversifying energy supply and reducing dependence on imported fuels.
Creating economic development and jobs in manufacturing, installation, and more.
drawbacks
Large areas of landfill are required
Hydroelectric power is generated from flowing water, which turns turbines and generates electricity
Explanation:
1) 2 kilograms converted into grams is 2000
2) 5200 meters converted into kilometers is 5.2
3) 20 centimeters converted into meters is 0.2
The new velocity after 4 s is 40 m/s
The height of the spaceship above the ground after 5 seconds is 1,127.5 m
The given parameters for the first question;
- initial velocity of the car, u = 76 m/s
- acceleration of the car, a = - 9 m/s²
The new velocity after 4 s is calculated as;
v = u + at
v = 76 + (-9)(4)
v = 76 - 36
v = 40 m/s
(5)
The given parameters;
- height above the ground, h = 500 m
- velocity of spaceship, u = 150 m/s
The height of the spaceship above the ground after 5 seconds is calculated as;
