As the problems discussed here are of projectile motion, that's why i am posting the problem that i have stuck in with...the problem says.. "A stone is thrown with a velocity u from the peak of a Pillar of height h from horizontal ground. the stone has hit the ground after traveling maximum...

Thanks for ur reply sir...

Homework Statement It says that "a man of mass m is standing on a ladder attached to the rope of a balloon of mass M (weight of the ladder and rope can be neglected). The balloon is in a static position. Now the man starts moving upwards through the ladder with a velocity v with respect to the...

now i understand ..thanks very much...

that's why i have done above...but i am confused that when i am using lami's theorem..i am getting different result...

i have drawn the diagram...can u pleasez help me out...

Static Problem...i am confused Homework Statement The Problem says " A rod is 5 ft long and its weight is 60 lb. one end of the rod is fastened to a vertical wall by a clip. other end is bound by a rop which is attached to point on the vertical wall situated at a 12 ft height from the clip...

ok...actually i can calculate the acceleration of the plane so that the block doesn't move...but , i am confused with the direction the force should be exerted to ...i mean, is the direction an issue regarding the force that to be exerted on the plane so that the block doesn't move...?? more...

well "accn" means acceleration...:shy:

i understand...thanks..but i want to know the horizontal direction of the force to be applied on the plane & also the accn the plane gets from the force satisfying that the block on the plane doesn't move. i want to get the concept that if the same force is exerted on the plane in opposite...

sorry..i didn't get it..can u please explain it briefly...

acceleration of the inclined plane ? Homework Statement A block of mass m is placed on an inclined plane. the angle of inclination is θ. now i want to understand in which direction (horizontal) the plane should be accelerated so that the block on it doesn't move. Homework Equations...

transfer of momentum...help needed ? Homework Statement two particles of masses m1 & m2 are moving along a straight line with velocities u & v respectively. they collide to each other..if the collision between them is an elastic collision then show that momentum transferred from first...

Thanks tiny-tm for the clarification...it seems that the sum has a printing mistake...
