A girl weighing 400 N climbs a vertical ladder. If the value of g be `10 m s^(-2)`, the work done by her after climbing 2 m will be :

A girl is carrying a school bag of 3 kg mass on her back and moves 200 m on a lavelled road. If the value of g be 10 m//s^(2) , the work done by the girl against the gravitational force will be :

A boy weighing 50 kg climbs up a vertical height of 100 m. Calculate the amount of work done by him. How much potential energy does he gain ? ( g = 9.8 m//s^(2) ).

A boy weighing 40 kg climbs up a vertical height of 200 m. calculate the amount of work done by him. How much potential, energy does the pain?

A uniform ladder of length 10.0 m and mas 16.0 kg is resting against a vertical smooth wall making an angle of 37^@ with it. An electrian weighing 60.0 kg climbs up the ladder. If the stays on the ladder at a point 8.00 m from the lower end, what will be normal force and the force of friction on the ladder by the ground? What should be the minimum coefficient of friction for the electician to work safely?

A boy of mass 40 kg climbs vertically upwards on a coconut tree to a height of 10m. Calculate the work done by the boy.

In a children\'s park, there is a slide which has a total length of 10 m and a height of 8.0 m figure. Vertical ladder are provided to reach the top. A boy weighting 200 N climbs up the ladder to the top of the slide and slides down to the ground. The averages friction offered by the slide is three tenth of his weight. Find a. the work done by the ladder on the boy as he goes up. b. the work done by the slide on the boy as he comes down. Neglect any work done by forces inside the body of the boy.
