Answer:
a) 20 seconds
b) No.
Explanation:
t = Time taken for jet to stop
u = Initial velocity = 100 m/s (given in the question)
v = Final velocity = 0 (because the jet will stop at the end)
s = Displacement of the jet (Distance between the moment the jet touches the ground to the point the point it stops)
a = Acceleration = -5.00 m/s² (slowing down, so it is negative)
a) Equation of motion
The time required for the plane to slow down from the moment it touches the ground is 20 seconds.
The distance it requires for the jet to stop is 1000 m so in a small tropical island airport where the runway is 0.800 km long the plane would not be able to land. The runway needs to be atleast 1000 m long here the runway on the island is 1000-800 = 200 m short.
Answer:
The magnitude of electron acceleration is
Explanation:
Given:
Distance from the wire to the field point m
Speed of electron
Current A
For finding the acceleration,
First find the magnetic field due to wire,
Where
T
The magnetic force exerted on the electron passing through straight wire,
N
From the newton's second law
Where mass of electron
kg
So acceleration is given by,
Therefore, the magnitude of electron acceleration is
