A gradener pushes a lawn roller through a distance 20 m. If he applies a force of 20 kg-wt in a direction inclined at 60^(@) to the ground, the work done by him is

A lawn roller has been pushed by a gardener through a distance of 30 m. What will be the work done by him, if he applies a force of 30 kg-wt in the direction inclined at 60^(@) to the ground?

A gardener pushes a lawn roller through a distance of 100m with a force of 50N Calcalye the wages if he is to be paid 10 paise for 25 J of work It is given that the applied force is inclined 60^(@) to the direction of motion .

A gardener moves a lawn roller through a distance of 100m with a force of 50N . Calculate his wages if he is to be paid 10 paise for doing 25J of work. It is given that the applied force is inclined at 60^@ to the direction of motion.

A gardener pushes a lawn roller on a rough surface. He applies a force of 150 N over a distance of 5 m. After he gets tired and his applied force reduces linerly with distance to 75 N. The total distance moved is 10 m. Plot the force applied by the gardencer and the frictional force, which is 75 N versus displacement. Calculate the work done by t he two forces over 10 m.

A lawn roller is displaced through 1 km using a force of 200 N in a direction making an angle of 60^(@) with the lawn .The work down is:

A force of 1200 N acting on a stone by means of a rope slides the stone through a distance of 10 m in a direction inclined at 60^@ to the force. The work done by the force is

A lawn roller is pulled along a horizontal surface through a distance of 20 m by a rope with a force of 200 N . If the rope makes an angle of 60^@ with the vertical while pulling, the amount of work done by pulling force is
