Rahul pushed a toy car and it moved a distance of 5 m. If the work done by Rahul is 1500 J, how much force did he apply through the push?

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?

Gopal travelled 125.5 km by bus, 14.25km by bike and the rest of distance of Kedarnath on foot. If he covered a total distance of 150km, how much did he travel on foot?

An object is pushed and pulled along a certain angle with respect to horizontal and is moved the some distance on the ground. Now the work done by frictional force will be more in

A girl having mass of 35 kg sits on a trolley of mass 5 kg. The trolley is given an initial velocity of 4m//s by applying a force. The trolley comes to rest after travelling a distance of 16m. (a) How much work is done on the trolley ? (b) How much work is done by the girl ?

A magnet is parallel to a uniform magnetic field. If it is rotated by 60^(@) , the work done is 0.8 J. How much work is done in moving it 30^(@) further

A man carries a load on his head through a distance of 5 m. The maximum amount of work is done when he

A block is pushed through 2m across is surface offering 25 N resistance. The work done by the resisting force

A body moves a distance of 10 m along a straight line under an action of 5 N force. If work done is 25 J, then angle between the force and firection of motion of the body will be :

A body is pushed through 5 m across a surface offering 75 N resistance How much work is done by the (1) applied force (ii) resisting force ?

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.
