A block is placed on a surface with vertical cross
section given by the equation y = 20
x2
. If the
coefficient of friction is 0.5, the maximum height
above the ground at which a block can be placed
without slipping is (Bottom most point of surface
is taken as origin and on ground) -
(A) 1.00 m (B) 1.25 m
(C) 1.50 m (D) 1.90 m
The potential energy (in joule) of a small block
of mass 2 kg moving in the x-y plane is given by
U = 6x + 8y
where the position coordinates x and y are
measured in metre. If the block is at rest at point
(6 m, 4m) at time t = 0, it will cross the y-axis at
time t equal to -
(A) 1 s (B) 2 s (C) 3 s (D) 4 s
