Answer:
50 m/s
Explanation:
The motion of the roller coaster car parameters are;
The initial speed of the roller coaster, v = 2 m/s
The distance to reach the bottom, Δd = 200 meter
The time it takes to reach the bottom, Δt = 4 seconds
The speed at the bottom of the tracks = 22 m/s
The average speed, = Δd/Δt
∴ = (200 m)/(4 s) = 50 m/s
The average speed of the roller coaster ride over the 200 m drop, = 50 m/s
Answer:
The answer is
<h2>468 , 750 J</h2>Explanation:
The kinetic energy of an object can be found by using the formula
where
m is the mass of the object
v is the speed or velocity
From the question
m = 1500 kg
v = 25 m/s
The kinetic energy of the object is
We have the final answer
<h3>468 , 750 J</h3>Hope this helps you
Answer:231.16 N/C
Explanation:
Given
Electric Flux
Area(A)
Given Field point above
Therefore angle between Area vector Electric Field =90-31.6=
We know that Flux is given by
