Question
A block of mass m is placed on a surface with a vertical cross-section given by y =
. If the coefficient of friction is 0.5, the maximum height above the ground at which the block can be placed without slipping is
. If the coefficient of friction is 0.5, the maximum height above the ground at which the block can be placed without slipping isOptions
A.
B.
C.
D.
Solution
tan θ =
At limiting equilibrium
μ= tan θ
0.5 =
⇒ x = ±1
Now, y =
