4 Best #bowlingTips For Bowling #Runup

In a second ODI match between England and India Bhuwnesh kumar bowled his medium fast bowling. He starts his run up from the distance of 50m from the stumps (bowling end) and at the time of bowling a ball,his speed is 36(km)//(hr) and the speed of ball is 144(km)//(hr) . If his mass is 70 kg and mass of the ball is (1)/(4)kg and the heat produce in his body is one tenth of the total work done by him, then Energy spent by bowler in throwing one ball is :-

If the coefficient of friction between an insect and bowl is mu and the radius of the bowl is r, find the maximum height to which the insect can crawl in the bowl.

A hemispherical bowl of radius R is set rotating about its axis of symmetry which is kept vertical. A small block kept in the bowl rotates with the bowl without slipping on its surface. If the surfaces of the bowl is smooth, and the angle made by the radius through the block with the vertical is theta , find the angular speed at which the bowl is rotating.

A hemispherical bowl of uniform mass distribution of mass ‘M’ is at rest on frictionless horizontal ground sur- face. There is a small insect of mass 'm' on bowl at point ‘A’ of the bowl at rest. Now the insect moves with constant speed ‘v’ relative to bowl in vertical plane. Assume that insect does not slip on the bowl. When insect at point ‘P’ on the bowl the displacement of centre of mass of the system (bowl + insect) is :

Now the insect moves with constant speed ‘v’ relative to bowl in vertical plane. Assume that insect does not slip on the bowl. When the insect is at point ‘P’ of the hemispherical bowl the acceleration of bowl is :

A black pattern on a porcelain bowl appears brighter than the rest of bowl, when it is strongly heated and taken to a dark room. This is an illustration of
