In a children's park, there si a slide which has a total length of 10 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.

A block of ice starts sliding down from the top of the inclined roof of a house (angle of inclination of roof= 30^(@) with the horizontal) along aline of maximum slope. The highest and lowest points of the roof are at heights of 8.1m and 5.6 m respectively from the ground. At what horizontal distance from the starting point will the block hit the ground? Neglect friction.

A box of mass 4 kg is placed on a wooden plank of length 1.5 m which is lying on the ground. The plank is lifted from one end along its length so that it becomes inclined. It is noted that when the vertical height of the top end of the plank from the ground becomes 0.5 m, the box begins to slide. Find the coefficient of friction between the box and the plank.

A body of mass Mkg is on the top point of a smooth hemisphere of radius 5m . It is released to slide down the surface of hemisphere it leaves the surface when its velocity is 5 ms^(−1) At this instant the angle made by the radius vector of the body with the vertical is ( Take g=10 m//s^(2) )

A block of mass 5.0kg slides down from the top of an inclined plane of length 3m . The first 1m of the plane is smooth and the next 2m is rough. The block is released from rest and again comes to rest at the bottom of the plane. If the plane is inclined at 30^@ with the horizontal, find the coefficient of friction on the rough portion.
