fun ques

Answer 1

In a game show, a smooth solid cylinder of mass \[M=50Kg\], radius \[r=77cm\] and density \[\rho=2.683Kgm^{-3}\] is placed above the ground at a height
\[h=10cm\]
A boy is asked to stand on the cylinder and run across the length
\[L\] of the cylinder when the game starts
When the game starts the cylinder starts moving with a velocity \[v_{o}=\sqrt{2}ms^{-1}\]
and starts rotating with about it's axis at an angular velocity \[\omega\]
to cover a distance of
\[d=20\sqrt{2}m\]
Given the total energy of the cylinder that is constant throughout as
\[E=125J\]
Find:
1)
\[t\]
the time taken by the cylinder to go from starting point to finishing point
2)
Length of the cylinder
\[L\]
3)
angular velocity \[\omega\]
4) the resultant velocity \[v\] with which the boy should move to just reach the end of the cylinder in time \[t\]
Use the following value for constants
\[g\approx10ms^{-2}\]
\[\pi\approx\frac{22}{7}\]

Answer 2

This is something I made

Answer 3

you invented the question?!?!

Answer 4

yep

Answer 5

Give it a try

Answer 6

cool!!

i certainly will do when i get a chance

a drawing would be good, just a sketch of course!!
