270333 A man slides down on a telegraphic pole with an acceleration equal to one-fourth of acceleration due to gravity. The frictional force between man and pole is equal to (in terms of man's weight\(W\) )

270334 A box is placed on the floor of a truck moving with an acceleration of\(7 \mathrm{~ms}^{-2}\). If the coefficient of kinetic friction between the box and surface of the truck is 0.5 ,find the acceleration of the box relative to the truck

270335 A block is placed at a distance of \(2 \mathrm{~m}\) from the rear on the floor of a truck \(\left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)\). When the truck moves with an acceleration of \(8 \mathrm{~ms}^{-2}\), the block takes \(2 \mathrm{sec}\) to fall off from the rear of the truck. The coefficient of sliding friction between truck and the block is

270336 Sand is piled up on a horizontal ground in the form of a regular cone of a fixed base of radius\(R\). The coefficient of static friction between sand layers is \(\mu\). The maximum volume of sand that can be piled up, without the sand slipping on the surface is
