A coolie is pushing a box weighing 1500 N up an inclined plane 7.5 m long on to a platform, 2.5 m above the ground.
Calculate the mechanical advantage of the inclined plane.

A coolie is pushing a box weighing 1500 N up an inclined plane 7.5 m long on to a platform, 2.5 m above the ground. Calculate the effort applied by the coolie.

A coolie is pushing a box weighing 1500 N up an inclined plane 7.5 m long on to a platform, 2.5 m above the ground. In actual practice, the coolie needs to apply more effort than what is calculated. Give one reason why you think the coolie needs to apply more effort.

A uniform ring rolls down an inclined plane without slipping. If it reaches the bottom of a speed of 2m//s , then calculate the height of the inclined plane (use g=10m//s^(2) )

A person pushes a block of mass 4 kg up a frictionless inclined plane 10 m long and that makes an angle of 30^@ with the horizontal . Then the work done is

A block is given velocity 10 m/s along the fixed inclined as shown in figure from the bottom of the inclined plane. Find the total distance travelled along the inclined plane. If the coefficient of friction is equal to 0.5

A person's eye is at a height of 1.5 m . He stands infront of a 0.3 m long plane mirror whose lower end is 0.8m above the ground. The length of the image he sees of himself is

A block kept on a rough inclined plane, as shown in the figure, remains at rest upto a maximum force 2N down the inclined plane. The maximum external force up the inclined plane that does not move the block is 10N. The coefficient of static friction between the block and the plane is : : [Taking g=10m//s^(2) ].

A disc of mass 3 kg rolls down an inclined plane of height 5 m. The translational kinetic energy of the disc on reaching the bottom of the inclined plane is

A block of mass m is lying on an inclined plane. The coefficient of friction between the plane and the block is mu . The force (F_(1)) required to move the block up the inclined plane will be:-
