Answer:
t = 3w/gk
y = w²/gk²(2+e^-gkt/t)
Explanation:
The detailed step by step solution can be found in the attachment below.
Vt = W/k. It is the velocity of the body when the drag force = the weight of the particle.
I steps have been explaine6in the attachments below.
Answer:
It would be static discharge and conduction
Explanation:
The conduction of static energy is pulled throughout the clothes and left over static electricity is what causes the spark.
The lowest constant acceleration needed for takeoff from a 1.80 km runway is 2.8 m/s².
To find the answer, we need to know about the Newton's equation of motion.
<h3>What's the Newton's equation of motion to find the acceleration in term of initial velocity, final velocity and distance?</h3>
- The Newton's equation of motion that connects velocity, distance and acceleration is V² - U²= 2aS
- V= final velocity, U= initial velocity, S= distance and a= acceleration
<h3>What's the acceleration, if the initial velocity, final velocity and distance are 0 m/s, 360km/h and 1.8 km respectively?</h3>
- Here, S= 1.8 km or 1800 m, V= 360km/h or 100m/s , U= 0 m/s
- So, 100²-0= 2×a×1800
=> 10000= 3600a
=> a= 10000/3600 = 2.8 m/s²
Thus, we can conclude that the lowest constant acceleration needed for takeoff from a 1.80 km runway is 2.8 m/s².
