By equation of motion we have S = ut + 0.5 a
Where u = Initail velocity, S= dispalcement, t = time taken, a = acceleration
Here S = 3500-400 = 3100m, u = 0m/s, g = 9.8 m/
So, 3100 = 0+0.5*9.8*
= 3100/4.9
t =
t = 25.15 seconds
Answer:
Part a)
Part b)
Explanation:
As we know that magnetic flux through the loop is given as
now we have
now rate of change in flux is given as
now we know that
Now plug in all data
Part b)
Now the radius of the loop after t = 1 s
Now plug in data in above equation
Answer:
2.0 s, 200 m
Explanation:
Time to hit the ground depends only on height. Since the plane is at the same height, the weight lands at the same time as before, 2.0 s.
Since the plane is going twice as fast, the weight will travel twice as far (ignoring air resistance). So it will travel a horizontal distance of 200 m.
