AND ENTRANCE EXHIBITIONS 681 ΠΙ φηίί If body be projected vertically upwards with velocity of 160 ft per second and another be projected with the same velocity from the same point at an angle of 60 to the horizon find the greatest height reached in each case and the time of reaching it State and explain the Third Law of Motion and show its application to the case of body falling under the action of gravity State the laws of the Conservation and the Transf orma- tion of Energy How is the energy of moving body estimated stone is let fall from the top of tower and another is thrown up from the ground at the same instant with velocity of 100 ft per sec when the stones meet they have the same velocity in opposite directions find the height of the tower There are four forces and 10 acting on point The angle between the first and second is 60 and between the second and third is 60 whilst that between the third ana fourth is 120 find the direction and magnitude of the resultant Find the relation between the power and weight on the first system of pulleys when there is equilibrium with four movable pulleys State the laws of friction The same force is required to support two equal masses on two given inclined planes one of which is smooth and the other has coefficient of friction of find what relation must hold between the inclinations of the two planes set of cubes of the same material whose edges are and inches are set in successive contact on table with one of the edges of each of the cubes coinciding with given straight line find the position of the centre of gravity of the cubes
