Answer:
Part a)
Moment of inertia of the cylinder is given as
Part B)
Height of the cylinder is of no use here to calculate the inertia
Part C)
Since we don't know about the viscosity data of the soup inside the cylinder so we can't say directly about the moment of inertia of the cylinder as
Explanation:
As we know that the inclined plane is of length L = 3 m
and its inclination is given as 25 degree
so we know that acceleration of center of mass of the cylinder is constant so we will have
so we have
now we know that
Now we have know that final speed of the cylinder due to pure rolling is given as
Part B)
Height of the cylinder is of no use here to calculate the inertia
Part C)
Since we don't know about the viscosity data of the soup inside the cylinder so we can't say directly about the moment of inertia of the cylinder as
Answer:
F =1490.9 N
Explanation:
given,
work done = 82 J
compression length = 0.220 m
for parallel combination
= 2 k
work done
force =
F = kx
F = 3388.43 ×0.22
F =745.45 N
the additional work done
final potential energy =
= 4 W = 328 J
the additional work = 328 - 82 = 255 J
maximum force
F = k × 2x
F = 2×745.45
F =1490.9 N
